You should be able to bubble custom events using the attachHandler and
fireEvents method on a widget.
I am still trying to conceive an example where you would need a custom event.
Most of the widely used events for all widgets have handlers defined.
I have not personally tried attaching a cus
In the @UIHandler example, you have a direct reference to the button
and you register a handler directly on the event source.
I was wondering if there's the possibility that some custom event goes

I come from the Flex/JS/Tapestry worlds and a technique commonly used
is to attach listeners to certain events expecting they'll will go up
like a bubble through the component hierarchy. Actually if I'm not

GWT.

and register those events with the eventBus. When ever that event occurs all
