Events

Type Phases Description
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 event might include the width of a column that supported client-side resizing.

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.RichPanelDashboard 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 Default Value: false

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.
columns int Yes Default Value: 3

the number of columns the width of the dashboard will be divided into
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.
dimensionsFrom String Yes Valid Values: auto, children, parent
Default Value: parent

determines how the component will handle geometry management. This specifies where the dimensions of the panelDashboard come from:

  • auto - either "children" or "parent", depending on the container the panelDashboard is inside; if the panelDashboard is being stretched by its ancestor then "parent" will be used, otherwise "children" will be used
  • children - the panelDashboard will get its dimensions from the children (rowHeight will still be honored so the contents of the rows will be constrained to those dimensions unless percent units are specified and then the default value will be used instead). Note that any height assignment (e.g. inlineStyle or styleClass) on the panelDashboard must be omitted or else there would be a competing assignment for how tall the component will be.
  • parent (the default) - the panelDashboard will get its dimensions from the inlineStyle and if not provided from there then from its parent or if not provided from the parent then from the skin
dropListener javax.el.MethodExpression Only EL A method reference to a callback with the signature oracle.adf.view.rich.dnd.DnDAction method(oracle.adf.view.rich.event.DropEvent dropEvent) called when a drop occurs on the component. Since the panelDashboard will automatically adjust the positions of its children in the browser, this method should return DnDAction.NONE if your handler is successful in adjusting the position of the reordered children since this will cause the panelDashboard to be left as is. If you return DnDAction.MOVE, the panelDashboard will be redrawn. You may wish to use org.apache.myfaces.trinidad.change.ReorderChildrenComponentChange and ChangeManager().addComponentChange() if you wish to preserve a new ordering of the children. Ideally, you should use an MDS ChangeManager to persist the change longer than the user's session so that the use does not have to repeatedly make the same reorder gesture every time your application is used. The dropEvent.getDropSiteIndex() method will give you the location that the user desires the dragged component to end up at. Use dropEvent.getTransferable().getData(DataFlavor.UICOMPONENT_FLAVOR) to get the dragged component.
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 ('-').
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. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. 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.
rendered boolean Yes Default Value: true

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.
rowHeight String Yes Default Value: 100px

the height of the rows of the grid layout as a CSS length. If dimensionsFrom resolves to "children", percent units are not allowed and the default value is used instead.
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'.
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. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.
visible boolean Yes Default Value: true

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
