Yes, it's actually a ResettableEventBus, so any handler added to it will automatically be removed when the activity is stopped/cancelled, and you don't have to track HandlerRegistrations yourself. Here's what the Javadoc says: """Any handlers attached to the provided event bus will be de- registered when the activity is stopped, so activities will rarely need to hold on to the HandlerRegistration instances returned by EventBus.addHandler(com.google.gwt.event.shared.GwtEvent.Type, H).""" http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/activity/shared/Activity.html#start(com.google.gwt.user.client.ui.AcceptsOneWidget, com.google.gwt.event.shared.EventBus) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
