JSF @ListenersFor

The @ListenersFor annotation allows you to register a component/renderer as a listener for multiple system events.

  @ListenersFor({
    @ListenerFor(systemEventClass=PostAddToViewEvent.class),
    @ListenerFor(systemEventClass=BeforeRenderEvent.class)
  })
  public class MyComponent extends UIComponentBase implements ComponentSystemEventListener {
    /*
     * @param event the event to handle.
     */
    public void processEvent(ComponentSystemEvent event) throws AbortProcessingException {
    }
  }
