Your HorizontalPanel was not added to a parent widget, so Widget.onAttach() was not called. This is where event handlers are setup.
You could hack your panel to call Widget.onAttach(), but there's probably a cleaner ways to do this. Can't you use RootPanel.get ("parentId").add(panel) to add your panel to the DOM tree? Then onAttach() is called automatically. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
