Hi

I'm trying to understand how could I use the annotation

I could subscribe to some event using this approach:

		eventBroker.subscribe(UIEvents.buildTopic(UIEvents.UIElement.TOPIC,
				UIEvents.UIElement.WIDGET), ev5);

and that is working properly and I always receive a Event object in 'ev5' handler.

Now I'm trying to do the same using UIEventTopic annotation. I've used this:

@Inject
	void processWindowEvents(
			@Optional @UIEventTopic(UIEvents.UIElement.TOPIC) Object event) {
		System.out.println(event);

	}

Its not seem to be working. It is being called once, but I think by the DI and the event parameter is always null.

I'm doing the right thing?

thanks

Cristiano
