Re: Events not firing or caught, though handlers created successfully

I suspect that the button widget is not properly added to the widget
tree through parentHasWidgets.add(buttonWidget)

Doing something like
parentDomElement.appendChild(buttonWidget.getElement()) will display
the button correctly but without any dom events being registered.
