Hi again, Tough crowd.... ha ha. I figured out how to fix my problem although I'm not entirely sure what was wrong with the initial code.
In order to get events firing, I can add the Composite widget instance to the RootPanel as oppose to appending the widget's root element to the document body. So instead of writing this and seeing the interface but not having any events: Document.get().getBody().appendChild(myView.getElement()); I can do this instead and events work properly: RootPanel.get().add(myView); I'm still interested in knowing why this is the case. I'm pretty sure the former code was not invented by me but copied from some tutorial out there.
