Hi ! We are encountering some memory leaks issues (mainly in IE of course) in our application that is based on the MVP pattern. After a deep code analysis we discovered that:
- We forgot to remove some handlers (using removeHandler() method from HandlerRegistration) on some custom widget we have created. - Some of the core GWT widget we use (such as DateBox or DialogBox) have some handler registrations that are never removed using the previous method. - Some of the handlers added in the bind() method of some presenters were also never removed, from the global EventBus or even on some widgets After reading some interesting documentation and other developpers experiences such as https://developers.google.com/web-toolkit/articles/dom_events_memory_leaks_and_you or http://www.draconianoverlord.com/2010/11/23/gwt-handlers.html it seems that removing handlers in the onUnload() method of a Widget seems to be pointless in most cases, as GWT already manage to do that ... and that would explain why some of the core GWT widgets don't even care to remove those handlers ... Does it worth going through each component on which we didn't unregistered some handlers in the onUnload method and unregister those handlers or is it just pointless, meaning that we should rather focus on the application part (EventBus, Presenters etc ...)? In a more general way, is there a way to detect (unit tests or integration tests) that all listeners of an event source are actually removed when they should have ?
