No, events do not bubble up (e.g. in Javascript). You can achieve a limited similar effect by using forwarding, but that will have to be done manually.

If you see any documentation that mentions "propagation", in ZK that just means the sequential execution of event listeners applied to a one common component. So, if you have added multiple event listeners to one component, you could stop propagation in the first one, and the latter ones would never see the event.

For your use case you can take a look at page.addEventListener, but I would strongly recommend you to figure out some other approach than that. Adding event listeners to all components on the page can have a huge negative effect on complex pages, and will not work for dynamically added components.

You can try to catch the onEvent method from the superclass of your controller. Works only for coded event methods.

public class MyTestComposer extends GenericForwardComposer {
   . . .


	@Override
	public void onEvent(Event evt) throws Exception {
		final Object controller = getController();
		final Method mtd = ComponentsCtrl.getEventMethod(controller.getClass(), evt.getName());

		// System.out.println(mtd.getName());

             // do your stuff here

	
	super.onEvent(evt);
	}
