JET Select Single

Description: JET Select Single provides support for single-select and search filtering.

A JET Select Single can be created with the following markup.


<oj-select-single data="[[dataProvider]]">
</oj-select-single>

Data

The only way to provide data to JET Select Single is through a DataProvider. Using <oj-option> and <oj-optgroup> child tags is not supported. For cases with a small set of fixed data, use an ArrayDataProvider.

Differences between Select and Combobox components

oj-select-* components and oj-combobox-* components may look and feel similar, but these components are different and are intended for very different use cases.

While oj-select-* components allow one to filter the data in the dropdown, it is not possible to enter values that are not available in the data. This makes oj-select-* components ideal for usecases where the user can only select values that are available in the dropdown, but not provide custom values of their own.

In contrast, oj-combobox-* components allow one to enter new values that are not available in the data in addition to using the text field for filtering dropdown data. This makes oj-combobox-* components ideal for usecases where the users can provide custom values in addition to those that are already available in the dropdown data.

Application developers should consider the above differences when choosing between Select and Combobox components. Additionally, applications are advised to use oj-select-single instead of the deprecated oj-select-one.

Validation and Messaging

An editable component runs validation (normal or deferred) based on the action performed on it (either by end-user or page author), and the state it was in when the action occurred. Examples of actions are - creating a component, user changing the value of the component by interacting with it, the app setting a value programmatically, the app calling the validate() method etc. At the time the action occurs, the component could already be showing errors, or can have a deferred error or have no errors.

These factors also determine whether validation errors/messages get shown to the user immediately or get deferred. The following sections highlight the kinds of validation that are run and how messages get handled.

Normal Validation

Normal validation is run in the following cases on the display value, using the converter and validators (this includes async-validators) set on the component, and validation errors are reported to user immediately.
  • When value changes as a result of user interaction all messages are cleared, including custom messages added by the app, and full validation is run on the UI value. The steps performed are outlined below.
    1. All messages are cleared and messagesCustom property is cleared
    2. If no converter is present then processing continues to next step. If a converter is present, the UI value is first converted (i.e., parsed). If there is a parse error then the messages are shown and processing returns.
    3. If there are no validators setup for the component then the value is set on the component. Otherwise all validators are run in sequence using the parsed value from the previous step. The implicit required is run first if the component is marked required. When a validation error is encountered it is remembered and the next validator in the sequence is run.
      • NOTE: The value is trimmed before required validation is run
    4. At the end of the validation run if there are errors, the messages are shown and processing returns. If there are async-validators, those errors are shown as soon as they come in, and not until all validators, sync and async validators, are complete, does processing return, that is, value and valid are updated. If there are no errors, then the value property is updated and the formatted value displayed on the UI.
  • When the validate method is called by app, all messages are cleared and full validation run using the display value. See validate method on the sub-classes for details. Note: JET validation is designed to catch user input errors, and not invalid data passed from the server; this should be caught on the server.
  • When certain properties change through programmatic intervention by app, the component determines whether it needs to run normal validation based on the state the component is in. Refer to the Mixed Validation section below for details.

Deferred Validation

Deferred validation is run in the following cases on the component value using the implicit required validator if required is true, and validation errors are deferred, i.e., not shown to user immediately. Refer to the Showing Deferred Messages section to understand how deferred messages can be shown.
  • When a component is created and it is required deferred validation is run and no messages are cleared prior to running validation. Refer to the Validators Participating in Deferred Validation section for details.
  • When the value property changes due to programmatic intervention deferred validation is run, after all messages and messagesCustom property are cleared.
  • When the reset method is called, deferred validation is run after all messages and messagesCustom property are cleared.
  • When certain properties change through programmatic intervention by app, the component determines whether it needs to run deferred validation based on the state the component is in. Refer to the Mixed Validation section below for details.

Mixed Validation

Either deferred or normal validation is run in the following cases based on the state the component is in and any validation errors encountered are either hidden or shown to user.
  • when disabled property changes. See disabled property for details.
  • when refresh method is called. See refresh method for details.
  • when converter property changes. Not all EditableValue components have the converter property. See the sub-classes that have the converter property for details, e.g., oj.ojInputText#converter.
  • when required property changes. Not all EditableValue components have the required property. See the sub-classes that have the required property for details, e.g., oj.inputBase#required.
  • when validators property changes. Not all EditableValue components have the validators property. See the sub-classes that have the validators property for details, e.g., oj.inputBase#validators.
  • when asyncValidators property changes. Not all EditableValue components have the asyncValidators property. See the sub-classes that have the asyncValidators property for details, e.g., oj.inputBase#asyncValidators.

Showing Deferred Messages

Deferred validation messages are displayed only when page author requests for it explicitly in one of the following ways:

Validators Participating in Deferred Validation

The required validator is the only validator type that participates in deferred validation. The required property needs to be set to true for the required validator to run.

User Assistance Text

User assistive text provides guidance to help the user understand what data to enter or select.

In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render, like in 'compact' mode, it will render as an icon on the label which when clicked will show the user assistance text in a notewindow.

The JET form component properties that are used for user assistance text are help.instruction, validator and converter hints, and help-hints. In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;
  • if no help.instruction, then validator hint shows;
  • if no help.instruction or validator hint, then help-hints.definition shows;
  • if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.
  • help-hints.source always shows along side the above.

In the Alta theme all the user assistance text are displayed to the user. By default help.instruction and the validator/converter hints show in a notewindow that is displayed when the field takes focus. The help-hints render as a help icon on the label and when clicked show in a notewindow. Note: If there is no label, help-hints help icon will not show.

Sometimes a validator or converter hints shows that you do not want. To not show it, set the display-options.validator-hint and/or display-options.converter-hint property to 'none'.

required and placeholder properties also can be used to guide the user. In Redwood, a required field shows the word Required under the field when the field is empty and does not have focus. Placeholder is shown when the field is empty and has focus.

Migration

Read about current Core Pack limitations to decide when to migrate.
Please make note of the following:

  • Deprecated APIs are not available in Core Pack, and are not documented in this migration section.
  • Before trying to migrate to Core Pack run the JET audits and fix any issues before proceeding.
  • The refresh() method is no longer supported in Core Pack. See the Core Pack Migration Guide for more information.

To migrate from oj-select-single to oj-c-select-single, you need to revise the import statement and references to oj-c-select-single in your app. Please note the changes between the two components below.

ItemText attribute

This attribute is required to specify how to get the text string to render for a data item.

LabelEdge attribute

The enum values for the label-edge attribute have been changed from 'inside', 'provided' and 'none' to 'start', 'inside', 'top' and 'none'. If you are using this component in a form layout and would like the form layout to drive the label edge of this component, leave this attribute unset. The application no longer has to specify 'provided' for this attribute. If you want to override how the label is positioned, set this attribute to the corresponding value.

MessagesCustom attribute

The type of the severity property of the messages in the array has changed from Message.SEVERITY_TYPE | Message.SEVERITY_LEVEL, essentially string | number, to simply 'error' | 'confirmation' | 'info' | 'warning'. These values are the same as the previously supported string values. The application can no longer specify severity as a number, including hardcoded numbers, one of the Message.SEVERITY_LEVEL constants, or the value returned from a call to the Message.getSeverityLevel method.

TextAlign attribute

The usage of the style classes: oj-form-control-text-align-right, oj-form-control-text-align-start and oj-form-control-text-align-end is now replaced with this attribute. The value of this attribute maps to these style classes as shown below:

  • .oj-form-control-text-align-right maps to 'right'
  • .oj-form-control-text-align-start maps to 'start'
  • .oj-form-control-text-align-end maps to 'end'

Translations

The instance level translations are not supported anymore for the following translation properties. These need to be configured in the translation bundle.

  • cancel
  • label-acc-clear-value
  • multiple-matches-found
  • n-or-more-matches-found
  • no-matches-found
  • one-match-found
The 'required' translation property can still be configured at the instance level, but this API is simplied to take a single string instead of an object. To show a different required message detail, the application can now set the `required-message-detail` attribute to the desired translated string.

ValueItem

The default value of the valueItem property is changed to null instead of { key: null, data: null, metadata: null }. Also, when clearing out the value of the component, this property will be set to null instead of the object mentioned above.

Refresh method

The refresh method is no longer supported. The application should no longer need to use this method. If the application wants to reset the component (remove messages and reset the value of the component), please use the reset method.

Animation Events

ojAnimateStart and ojAnimateEnd events are no longer supported.

ojValueAction Event

When clearing out the value, the itemContext property of the event.detail object will be set to null instead of { key: null, data: null, metadata: null }.

Custom Label

Adding a custom <oj-label> for the form component is no longer supported. The application should use the label-hint attribute to add a label for the form component.

The application should no longer need to use the <oj-label-value> component to layout the form component. The application can use the label-edge attribute and label-start-width attribute to customize the label position and label width (only when using start label).

DescribedBy attribute

The described-by attribute is not meant to be set by an application developer directly as stated in the attribute documentation. This attribute is not carried forward to the core pack component.

Usage in Dynamic Form

Using the component in oj-dyn-form is not supported in this release, use oj-dynamic-form instead.

Limitations

Note that oj-c-select-single supports a limited feature set in JET 16. It does not support:

  • hierarchical data
  • customizing dropdown content by providing a customized collection component (no collectionTemplate)

Performance

Page Load

If there is an initially selected value, setting the valueItem attribute initially can improve page load performance because the element will not have to fetch the selected label from the data provider.

The dropdown data isn't fetched until the user opens the dropdown.

Reading direction

As with any JET element, in the unusual case that the directionality (LTR or RTL) changes post-init, the Select must be refresh()ed.

Accessibility

The element will decorate its associated label with required and help information, if the required and help attributes are set.

For accessibility, set label-hint or associate an oj-label with the form component. If there is no visible label, then to make this accessible to screen reader users, set the label-hint and label-edge='none' which renders an aria-label with the label-hint text. If using an oj-label instead of the label-hint attribute, then put an id on the form component element, and set the oj-label's for attribute to be the form component's id.

The placeholder text is not read reliably by the screen reader. For accessibility reasons, you need to associate the text to its JET form component using aria-describedby.

Disabled content: JET supports an accessible luminosity contrast ratio, as specified in WCAG 2.0 - Section 1.4.3 "Contrast", in the themes that are accessible. (See the "Theming" chapter of the JET Developer Guide for more information on which themes are accessible.) Note that Section 1.4.3 says that text or images of text that are part of an inactive user interface component have no contrast requirement. Because disabled content may not meet the minimum contrast ratio required of enabled content, it cannot be used to convey meaningful information.

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

collectionTemplate

The collectionTemplate slot is used to specify the template for rendering the items in the dropdown. The slot must be a <template> element containing a child collection element (e.g. <oj-table>) supporting single selection. The data, selected, and selectedItem properties should be set on the appropriate collection component attributes, e.g. data, selected, and first-selected-item for oj-list-view and data, selected.row, and first-selected-row for oj-table. Note as well that the selectedItem must be bound using a writeback expression (i.e. {{$current.selectedItem}}) so that it can be updated when the user selects a new value. The oj-select-results class must also be applied to the collection element in the template.

When the template is executed, it will have access to the binding context containing the following properties:

  • $current - an object that contains information for the collection. (See the table below for a list of properties available on $current)
  • alias - if the data-oj-as attribute was specified on the template, the value will be used to provide an application-named alias for $current.

If no collectionTemplate is specified, the component will check whether an itemTemplate is specified. Otherwise, the component will render based on the value of the itemText property.

Properties of $current:
Name Type Description
currentRow Object

The currentRow property is used to set the focus to current active row in the oj-table. This is also used to get the key for the current row when navigating through the options in the dropdown. Since, this property is used to listen to the changes made by the oj-table, it should be bound to the current-row attribute of the oj-table

using a writable expression.

Example:

           
             <oj-table
               ...
               current-row="{{$current.currentRow}}"
               ...>
Properties
Name Type Description
rowKey V

When using oj-list-view, this sub-property of the currentRow property should be used instead. This should be bound to the current-item attribute of the oj-list-view

using a writable expression.

Example:

           
             <oj-list-view
               ...
               current-item="{{$current.currentRow.rowKey}}"
               ...>
data DataProvider.<V, D> The data for the collection.
handleRowAction ((event: Event, context: ojcommontypes.ItemContext<V, D>) => void)

The handleRowAction property is used to make selection for oj-select-single when ojItemAction is triggered in the oj-list-view (ojRowAction if oj-table is used).

This should be bound to the on-oj-item-action attribute of oj-list-view if it is used for the collectionTemplate.

When using oj-table as the collectionTemplate this should be bound to the on-oj-row-action attribute of the oj-table instead.
searchText string Search text.
selected KeySet.<V>

The selected property is used to push the current selected option to the collection. This is also used to highlight the option when navigating through the dropdown.

This should be bound to the selected attribute of oj-list-view if it is used for the collectionTemplate.

When using oj-table as the collectionTemplate this should be bound to the selected.row attribute of the oj-table instead.
selectedItem ojcommontypes.ItemContext.<V, D> The selected item context.
Deprecated:
Since Description
9.0.0 The selectedItem property is deprecated in favor of currentRow and handleRowAction properties, which provide additional functionalities.

itemTemplate

The itemTemplate slot is used to specify the template for rendering each item in the dropdown list when an external collectionTemplate is not provided. The slot must be a <template> element.

When the template is executed for each item, it will have access to the binding context containing the following properties:

  • $current - an object that contains information for the current item. (See the table below for a list of properties available on $current)
  • alias - if the data-oj-as attribute was specified on the template, the value will be used to provide an application-named alias for $current.

If no itemTemplate or collectionTemplate is specified, the component will render based on the value of the itemText property.

Note that the properties depth, leaf, parentKey, are only available when the supplied dataProvider is a TreeDataProvider.

Properties of $current:
Name Type Description
componentElement Element The Select custom element
data D The data for the current item being rendered
depth number (TreeDataProvider only) The depth of the current item (available when hierarchical data is provided) being rendered. The depth of the first level children under the invisible root is 1.
index number The zero-based index of the current item
key V The key of the current item being rendered
leaf boolean (TreeDataProvider only) True if the current item is a leaf node (available when hierarchical data is provided).
metadata oj.ItemMetadata<V> The metadata for the current item being rendered
parentKey V (TreeDataProvider only) The key of the parent item (available when hierarchical data is provided). The parent key is null for root nodes.
searchText string The search text entered by the user

Attributes

data :DataProvider.<V, D>

The data for the Select.

Note that the item-text attribute and the itemTemplate and collectionTemplate slots allow for customizing the rendering of each data item. If those are not specified, then the component will attempt to render as text the 'label' field in the data item by default.

disabled :boolean

Whether the component is disabled. The default is false.

When the disabled property changes due to programmatic intervention, the component may clear messages and run validation in some cases.

  • when a required component is initialized as disabled value="{{currentValue}}" required disabled, deferred validation is skipped.
  • when a disabled component is enabled,
    • if component is invalid and showing messages then all component messages are cleared, and full validation run using the display value.
      • if there are validation errors, they are shown.
      • if no errors result from the validation, the value property is updated. Page authors can listen to the valueChanged event to clear custom errors.
    • if component is valid and has no errors then deferred validation is run.
      • if there is a deferred validation error, then the valid property is updated.
    • if component is invalid and deferred errors then component messages are cleared and deferred validation re-run.
      • if there is a deferred validation error, then the valid property is updated.
  • when enabled component is disabled then no validation is run and the component appears disabled.

display-options :Object

Display options for auxiliary content that determines whether or not it should be displayed.

In the Redwood theme, the sub-properties of the display-options configure whether or not the types of information is shown. The values of these sub-properties are either 'display' or 'none'.

In the Alta theme the sub-properties of the display-options configure aspects of visual behavior such as where types of information is shown. The values of these sub-properties are specified either as an array of strings or a string. When an array is specified the first display option takes precedence over the second display option and so on.

When display-options changes due to programmatic intervention, the component updates its display to reflect the updated choices. For example, if you don't want to show the message, set the display-options.messages to 'none'.

A side note: help.instruction and message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. To format the help.instruction, you could do this: 

<html>Enter <b>at least</b> 6 characters</html>

display-options.messages :Array<'inline'|'notewindow'|'none'>|'inline'|'notewindow'|'display'|'none' display-options.messages :('display'|'none')

Display options for auxiliary message text. The supported attribute values are theme dependent.

In the Redwood theme, this attribute determines whether or not the messages should be displayed. The suppoorted values are 'display' and 'none'. If you don't want to show messages, set display-options.messages to 'none'. It defaults to 'display'. To control where the messages display, e.g., inline or in a notewindow, then use the user-assistance-density attribute.

In the Alta theme this attribute determines where and whether to show the messages. If you don't want to show messages, set display-options.messages to 'none'. The Alta theme supports these attribute values, most of which are deprecated: Array<'inline'|'notewindow'|'none'>|'inline'|'notewindow'|'none'. The default is ['inline'].

Deprecated:
Since Value Description

help.instruction :string

A type of user assistance text. User assistance text is used to provide guidance to help the user understand what data to enter or select.

In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;
  • if no help.instruction, then validator hint shows;
  • if no help.instruction or validator hint, then help-hints.definition shows;
  • if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.
  • help-hints.source always shows along side the above.

In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render.

In Alta theme, help.instruction displays in a notewindow when the field takes focus. How is help.instruction better than the html 'title' attribute? The html 'title' attribute only shows up as a tooltip on mouse over, not on keyboard and not in a mobile device. So the html 'title' would only be for text that is not important enough to show all users, or for text that you show the users in another way as well, like in the label. Also you cannot theme the native browser's title window like you can the JET notewindow, so low vision users may have a hard time seeing the 'title' window. For these reasons, the JET EditableValue components do not use the HTML's 'title' attribute and instead use the help.instruction attribute.

To include formatted text in the help.instruction, format the string using html tags. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. For example the help.instruction might look like: 

<oj-some-element help.instruction="<html>Enter <b>at least</b> 6 characters</html>"></oj-some-element>
If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there.

A type of user assistance text. User assistance text is used to provide guidance to help the user understand what data to enter or select. help-hints could come from a help system.

In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;
  • if no help.instruction, then validator hint shows;
  • if no help.instruction or validator hint, then help-hints.definition shows;
  • if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.

In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render.

In the Alta theme the help-hint.definition shows up when the user hovers over the help icon on the label, or tabs into the help icon, or press and holds the help icon on a mobile device.

No formatted text is available for help definition attribute.

(nullable) help-hints.source :string

Help source URL associated with the component.

In the Redwood theme, the help-hints.source will show as a link inline to the field. For input components, it shows when the field takes focus. For other components, it shows all the time.

In the Alta theme, the help-hints.source will show as a a help icon next to the label. When clicked the page will navigate to the source url.

For security reasons we only support urls with protocol 'http:' or 'https:'. If the url doesn't comply we ignore it and throw an error. Pass in an encoded URL since we do not encode the URL.

item-text :keyof D | ((itemContext: ojcommontypes.ItemContext<V, D>) => string)

Specifies the text string to render for a data item. This attribute can be set to either:
  • a string that specifies the name of a top level data field to render as text, or
  • a callback function that takes a context object and returns the text string to display

By default, the component will attempt to render a 'label' data field as text.

This text will be rendered for the selected value of the component. It will also be rendered for each data item in the dropdown if no itemTemplate or collectionTemplate is provided. When rendered for the dropdown items, default matching search term highlighting will still be applied.

label-edge :('inside'|'none'|'provided')

Specifies how the label of the component is created when the label-hint attribute is set on the component.

The default value varies by theme, and it works well for the theme in most cases. If the component is in an oj-form-layout, the label-edge attribute could come from the oj-form-layout's label-edge attribute. The oj-form-layout component uses the MetadataTypes.PropertyBinding provide property to provide and uses the MetadataTypes.ProvideProperty transform property to transform its label-edge attribute to any descendent components that are configured to consume it. For example, if the oj-form-layout's label-edge attribute is set to "top" or "start", and a descendent form component does not have its label-edge attribute set, the form component's label-edge will be the transformed value "provided".

Supported Values:
Value Description
inside The component creates the label using the label-hint attribute.

For text input components (such as oj-input-text), the label floats over the input element but moves up on focus or when the component has a value.

For non-text input components (such as oj-checkboxset), the label is created at the top of the component and doesn't move.
none The component will not have a label, regardless of whether it's in an oj-form-layout or not.

If the component has a label-hint attribute but no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.

Note that if the component already has an external label, "none" should not be specified and "provided" should be used instead. Otherwise it may end up with conflicting label information.
provided Label is provided by the parent if the parent is an oj-form-layout.

oj-form-layout provides the label using the label-hint from the form control and the label-edge from oj-form-layout.

If there is no oj-form-layout, use an oj-label.

label-hint :string

Represents a hint for rendering a label on the component.

This is used in combination with the label-edge attribute to control how the label should be rendered.

When label-edge is "provided", it gives a hint to oj-form-layout parent element to create an oj-label element for the component. When the label-hint attribute changes, oj-form-layout element refreshes to display the updated label information.

When label-edge is "inside", it gives a hint to the component itself to render a label.

When label-edge is "none", and if the component has no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.

labelled-by :string|null

The oj-label sets the labelledBy property programmatically on the form component to make it easy for the form component to find its oj-label component (a document.getElementById call.)

The application developer should use the 'for'/'id api to link the oj-label with the form component; the 'for' on the oj-label to point to the 'id' on the input form component. This is the most performant way for the oj-label to find its form component.

messages-custom :Array<oj.Message>

List of messages an app would add to the component when it has business/custom validation errors that it wants the component to show. This allows the app to perform further validation before sending data to the server. When this option is set the message shows to the user right away. To clear the custom message, set messagesCustom back to an empty array.

Each message in the array is an object that duck types oj.Message. See Message for details. message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. To format the message detail, you could do this: 

<html>Enter <b>at least</b> 6 characters</html>

See the Validation and Messages section for details on when the component clears messagesCustom; for example, when full validation is run.

In the Redwood theme, the Message summary is not displayed to the user, so make sure to have a Message detail set in your Message object.

readonly :boolean

Dictates element's readonly state.

The default value for readonly is false. However, if the form component is a descendent of oj-form-layout, the default value for readonly could come from the oj-form-layout component's readonly attribute. The oj-form-layout uses the MetadataTypes.PropertyBinding provide property to provide its readonly attribute value to be consumed by descendent components. The form components are configured to consume the readonly property if an ancestor provides it and it is not explicitly set. For example, if the oj-form-layout's readonly attribute is set to true, and a descendent form component does not have its readonly attribute set, the form component's readonly will be true.

required :boolean

This property set to false implies that a value is not required to be provided by the user. This is the default. This property set to true implies that a value is required to be provided by the user.

In the Redwood theme, by default, a Required text is rendered inline when the field is empty. If user-assistance-density is 'compact', it will show on the label as an icon. In the Alta theme the input's label will render a required icon.

The Required error text is based on Redwood UX designs, and it is not recommended that it be changed. To override the required error message, use the translations.required attribute. The component's label text is passed in as a token {label} and can be used in the message detail.

When required is set to true, an implicit required validator is created, i.e., new RequiredValidator(). The required validator is the only validator to run during initial render, and its error is not shown to the user at this time; this is called deferred validation. The required validator also runs during normal validation; this is when the errors are shown to the user. See the Validation and Messaging section for details.

When the required property changes due to programmatic intervention, the component may clear component messages and run validation, based on the current state it's in.

Running Validation when required property changes

  • if component is valid when required is set to true, then it runs deferred validation on the value property. If the field is empty, the valid state is invalidHidden. No errors are shown to the user.
  • if component is invalid and has deferred messages when required is set to false, then component messages are cleared (messages-custom messages are not cleared) but no deferred validation is run because required is false.
  • if component is invalid and currently showing invalid messages when required is set, then component messages are cleared and normal validation is run using the current display value.
    • if there are validation errors, then value property is not updated and the error is shown.
    • if no errors result from the validation, the value property is updated; page author can listen to the valueChanged event on the component to clear custom errors.

Clearing Messages when required property changes

  • Only messages created by the component, like validation messages, are cleared when the required property changes.
  • messagesCustom property is not cleared.

user-assistance-density :('reflow'|'efficient'|'compact')

Note: This attribute is not supported in the following themes: Alta

Specifies the density of the form component's user assistance presentation. It can be shown inline with reserved rows to prevent reflow if a user assistance text shows up, inline without reserved rows that would reflow if a user assistance text shows up, or it can be shown compactly in a popup instead.

The default value is 'reflow' when the form component is not a descendent of an oj-form-layout component. When the form component is a descendent of an oj-form-layout, the default value comes from the oj-form-layout's user-assistance-density attribute value.

The oj-form-layout component uses the MetadataTypes.PropertyBinding provide property to provide its user-assistance-density attribute value to be consumed by descendent components. The form components are configured to consume the user-assistance-density property if an ancestor provides it and it is not explicitly set on the form component. Example, oj-form-layout defaults user-assistance-density='efficient', so all its form components descendents will have user-assistance-density='efficient' by default.

Supported Values:
Value Description
compact Messages, help, hints, and required will not be shown inline; they will show in a mode that keeps the screen more compact, like a popup for the messages, and a required icon to indicate Required.

(readonly) valid :"valid"|"pending"|"invalidHidden"|"invalidShown"

The current valid state of the component. It is evaluated on initial render. It is re-evaluated

  • after each validator (validators or async-validators) is run (full or deferred)
  • when messagesCustom is updated, since messagesCustom can be added by the app developer any time.
  • when showMessages() is called. Since showMessages() moves the hidden messages into messages shown, if the valid state was "invalidHidden" then it would become "invalidShown".
  • when the required property has changed. If a component is empty and has required set, the valid state may be "invalidHidden" (if no invalid messages are being shown as well). If required property is removed, the valid state would change to "valid".

Note: New valid states may be added to the list of valid values in future releases. Any new values will start with "invalid" if it is an invalid state, "pending" if it is pending state, and "valid" if it is a valid state.

Supported Values:
Value Description
invalidHidden The component has invalid messages hidden and no invalid messages showing. An invalid message is one with severity "error" or higher.
invalidShown The component has invalid messages showing. An invalid message is one with severity "error" or higher.

The valueItem is similar to the value, but is a ItemContext<V, D> object which contains both a key and data, and optional metadata. The key will be set as the value of the element. The value and valueItem are kept in sync, both during programmatic property sets as well as during interactive user selection. If initially both are set, the selected value in the value attribute has precedence.

Note: If there is an initial selection, setting it via the valueItem attribute initially can improve page load performance because the element will not have to fetch the selected data from the data provider.

ojAnimateStart

Triggered when a default animation is about to start on an element owned by the component.

The default animation can be cancelled by calling event.preventDefault, followed by a call to event.detail.endCallback. event.detail.endCallback should be called immediately after event.preventDefault if the application merely wants to cancel animation, or it should be called when the custom animation ends if the application is invoking another animation function. Failure to call event.detail.endCallback may prevent the component from working properly.

For more information on customizing animations, see the documentation of AnimationUtils.

The default animations are controlled via the theme:

handleRowAction ((event: Event, context: ojcommontypes.ItemContext<V, D>) => void)

The handleRowAction property is used to make selection for oj-select-single when ojItemAction is triggered in the oj-list-view (ojRowAction if oj-table is used).

This should be bound to the on-oj-item-action attribute of oj-list-view if it is used for the collectionTemplate.

When using oj-table as the collectionTemplate this should be bound to the on-oj-row-action attribute of the oj-table instead.
searchText string Search text.
selected KeySet.<V>

The selected property is used to push the current selected option to the collection. This is also used to highlight the option when navigating through the dropdown.

This should be bound to the selected attribute of oj-list-view if it is used for the collectionTemplate.

When using oj-table as the collectionTemplate this should be bound to the selected.row attribute of the oj-table instead.
