Custom Wicket Event Message Example

CustomContainer.java

class CustomContainer extends WebMarkupContainer {

	public CustomContainer(String id) {
		super(id);
	}

	@override
	public void onBeforeRender() {
		// Some form do forward message passing for
                // All Pages/Componets implements IEventSource
		final Form<Void> form = new Form<Void>("formId") {
                        
			@Override
			protected void onSubmit() {
				super.onSubmit();
				send(getApplication(), Broadcast.BREADTH, this.getParent()); // forward by using send
			}
		};
	}
}

CustomPage.java

class CustomPage extends WebPage {
        protected static Logger LOG = LoggerFactory.getLogger(CustomPage.class);

	public CustomPage() {
	}

        // Our EventSink, alle pages, components implements IEventSink
	@Override
	public void onEvent(IEvent<?> event) {
		if ((event.getPayload()) instanceof CustomContainer) {
			LOG.debug("We received an event from the CustomContainer with id: {}", ((CustomContainer) (event.getPayload).getId()) );
			// Stop bubbling the event
			event.stop();
		}
		else {
                        // we where not meant  to receive this event continue bubbling
			super.onEvent(event);
		}
	}
