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 events 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 | org.apache.myfaces.trinidad.component. |
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. |
generatesContent | boolean | Yes | Default Value:
false if the script generates content using document.write() or document.writeln(), set this to true. It defaults to false. |
id | String | No | the identifier for the component. The identifier
must follow a subset of the syntax allowed in HTML:
|
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. |
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. |
source | String | Yes | the URI of a script library to import. |
text | String | Yes | the inline script |
