See javadoc of Activity#start: 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<http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/event/shared/HandlerRegistration.html> instances returned byEventBus.addHandler(com.google.gwt.event.shared.GwtEvent.Type, H)<http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/event/shared/EventBus.html#addHandler(com.google.gwt.event.shared.GwtEvent.Type, H)>.
So when you stop, then eventbus is "clean". 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) <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)> 2011/5/9 Thomas Lefort <[email protected]> > Hi, > > I use the ResettableEventBus passed to my activity in the start method > to register my event handlers for the activity. > The way my application works is that each time a "project" is loaded, > the activity makes a call to the placeController goTo method to reload > the activity with the right project id. This is all done within the > same activity type. > Before I can load the project I need to wait for resources to be > loaded. Once they are loaded I can load the prject itself.
