org.ajax4jsf.component.behavior.AjaxBehavior

The <a4j:ajax> behavior allows Ajax capability to be added to a non-Ajax component. The non-Ajax component must implement the ClientBehaviorHolder interface for all the event attributes that support behavior rendering.

org.apache.click.ajax.AjaxBehavior
AjaxBehavior extends the basic Behavior functionality to allow Controls to handle and process incoming Ajax requests.
To handle an Ajax request, AjaxBehavior exposes the listener method: {@link #onAction(org.apache.click.Control) onAction}. The onAction method returns an ActionResult that is rendered back to the browser.
Before Click invokes the onAction method it checks whether the request is targeted at the AjaxBehavior by invoking the method {@link #isAjaxTarget(org.apache.click.Context) Behavior.isAjaxTarget()}. Click will only invoke onAction if isAjaxTarget returns true.
