serverListener server listener

The serverListener tag is a declarative way to register a server-side listener that should be executed when a custom client event is fired. This tag will be ignored for any server-rendered components, as it is only supported for the rich client. The target method must return void and take one argument, a ClientEvent object.

To fire a custom event from the client, use the AdfCustomEvent.queue() Javascript method:

 * Convenience function for queueing an Custom event from a component.
 * @param {AdfUIComponent} Component to queue the custom event on
 * @param {String} the type of the event
 * @param {Object} a set of parameters to include on the event.  Reserved
 *    parameter names include "type" and "immediate".
 * @param (boolean) whether the custom event is "immediate" - which will
 *  cause it to be delivered during Apply Request Values on the server,
 *  or not immediate, in which case it will be delivered during
 *  Invoke Application. 
 * @final
AdfCustomEvent.queue = function(component, type, params, immediate) { ... }



This example will invoke the doCustomEvent() method on the server when a custom event of type "myCustomEvent" is sent to this component.

            var inputComp = someOtherComp.findComponent("myInput");
                                 // Send one parameter
                                 // Make it "immediate" on the server
            <af:inputText clientComponent="true" id="myInput" value="Can send custom events">
                <af:serverListener type="myCustomEvent" method="#{bean.doCustomEvent}"/>


             public void doCustomEvent(ClientEvent event)
               if (Boolean.TRUE.equals(event.getParameters().get("skyIsFalling")))
                 ... ;
