But what I don't get is why you don't want to explicitly clean things up? If you rely on WeakRef or anything similar you depend on garbage collection, which isn't really great since you never know when GC will happen and behavior is different between browsers. So if you have an EventBus that uses some weak references it is likely designed as "if nobody has a strong reference to a registered event handler, then remove that event handler from the event bus". The problem is that you can not control GC and as long as GC does not run, these handlers will still get events, regardless if your app still uses these classes or not. So you have overhead until the browser decides to run GC and clean these weak references. I would try to refactor code to make explicit event bus registration and deregistration easier and less error prone. For example take GWT Activities. The EventBus you get in its start() method is automatically cleaned up as soon as the activity stops. I am pretty sure there are options to build some classes around your existing ones to better deal with EventBus. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
