I've stepped through the code and there is no requirement to unregister handlers explicitly. Each widget has a handler manager (as member variable) that manages its handlers. If a widget is removed from its parent or its parent explicitly clears it then the registered handlers will get cleaned up by normal garbage collection.
This is not the case if you are using a global handler manager for say an event bus. If handlers are added that are specific to a particular presenter then the presenter needs to remove the handlers when it is destroyed. I implemented a Place Manager that takes care of all of this automatically along with history support. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
