You could also access private members through JSNI (which bypasses Java 
access rules).

And in the case of the list in ListHandler, you can modify its content 
rather than replacing it: lh.getList().clear(); 
lh.getList().addAll(newList) 

(I don't see any "elements" or "widgets" in DialogBox.CaptionImpl; not sure 
what's being asked here)
