af:showDetail showDetail show detail

UIComponent class: oracle.adf.view.rich.component.rich.layout.RichShowDetail
Component type: oracle.adf.RichShowDetail

The showDetail provides a means of toggling a group of components between being disclosed or undisclosed. A showDetail should be used to:

On mobile devices the showDetail renders nothing itself, but does renders its children.

Appearance

The appearance of the showDetail is dependent upon the disclosed, disclosedText, and undisclosedText properties, as well as the presence of a prompt facet. If you do not specify a "disclosedText" property for the component, the text "Hide" will be used instead. If you do not specify an "undisclosedText" property for the component, the text "Show" will be used instead. Alternatively, you can specify your own prompt by using the "prompt" facet.

Events

Clicking on the icon of the showDetail will deliver a DisclosureEvent to the server. If a "prompt" facet is used, changing the value of the disclosed attribute on this component will also deliver the event.

Unsupported Attributes

The disclosedTransient attribute is not supported by the rich client renderers and may only be used with the Apache MyFaces Trinidad RenderKit. If this attribute is set to true in an ADF page, the component will not function correctly. This attribute appears in ADF due to it being inherited from UIXShowDetail. The value must either not be set, or must be set to false, a value of true will cause problems.

Attachment Mode

In Attachment Mode, contentDelivery will be forced to contentDelivery="immediate"

Code Example(s)

An interactive showDetail

<af:showDetail id="showDetail1">
  <af:panelHeader text="Header" />
</af:showDetail>
   

Events

Type Phases Description
org.apache.myfaces.trinidad.event.DisclosureEvent Apply Request Values,
Invoke Application
The disclosure event is delivered when a node is disclosed.
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application,
Apply Request Values
Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.

Supported Facets

Name Description
prompt Component rendered next to the hide or show icon. If this facet is present, this will be used instead of the disclosedText and undisclosedText attributes.

Attributes

Name Type Supports EL? Description
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding oracle.adf.view.rich.component.rich.layout.RichShowDetail Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
clientComponent boolean Yes whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.
contentDelivery String Yes Valid Values: immediate, lazyUncached

whether the undisclosed content is delivered with the initial page. When contentDelivery is "immediate", the content is inlined into the initial page. If contentDelivery is "lazy", the content will be delivered to the client only after the first request to disclose the component. If contentDelivery is "lazyUncached", the content will be delivered each and every time the component's disclosure changes. By default, contentDelivery is lazyUncached.
customizationId String Yes This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
disclosed boolean Yes whether or not to disclose the children
disclosedText String Yes the text to display when the children are disclosed. If this attribute is set and the undisclosedText attribute is not set, this text will be displayed for both the disclosed state AND the undisclosed state.
disclosedTransient boolean Yes stops the local value of disclosed from being set by renderers. This allows the value to always be taken from the value of the disclosed value expression. Disclosed values must be updated in other ways (i.e. from a disclosure listener)
disclosureListener javax.el.MethodExpression Only EL a method reference to a disclosure listener
dontPersist String[] Yes a list of attributes whose changes are NOT to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be excluded. If there is a conflict of values, "dontPersist" always precedes "persist".
id String No the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
  • Must not be a zero-length String.
  • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
  • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
immediate boolean Yes whether data validation - client-side or server-side - should be skipped when events are generated by this component. When immediate is false (the default), the disclosure event will be delivered during the Invoke Application phase, which will trigger validation. When set to true, the disclosure event will be executed during the Apply Request Values phase.
inlineStyle String Yes the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.
partialTriggers String[] Yes the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.
persist String[] Yes a list of attributes whose changes are to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be included.
rendered boolean Yes whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
shortDesc String Yes the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.
styleClass String Yes a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.
undisclosedText String Yes the text to display when the children are undisclosed. If this attribute is set and the disclosedText attribute is not set, this text will be displayed for both the disclosed state AND the undisclosed state.
unsecure java.util.Set Yes A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute.
visible boolean Yes the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
