Hi all, I want to check my application for memory leaks. Can you help me?
I installed JProfiler 8 and attached it to debug moded jetty (ran from eclipse plugin) and checked the live heap objects. Every created component exists in the heap and never gc'ed until page refresh. When i looked at the objects i cant see a circular reference (incoming refs) except some com.gwt... classes in fields named target and/or source. Is that normal in Debug&DevMode ran from Eclipse since not translated to Javascript? One more related important question is; I have a composite widget named Form. Its a composition of objects and handlers. It has 3 textboxes and 1 button defined as global/field in class and created in class constructor and put to a SimplePanel area via Grid. Button has an anonymously implemented click handler. In JProfiler the anonymously implemented class instance exists in the heap and never gc'ed (same as above case, Debug&DevMode from Eclipse). And the button and the composite instances seem to be cycle referenced because of SimplePanel doesnt release inner widget. So i invoked SimplePanel object's setWidget(null) on onUnload but didnt remove buttons click handler. At this point; Can i accept these as normal and wont worry about memory leak? or is that a really problem and i should nullify button,textboxes in the onUnload method? In anyway do i need to remove click handler from button? Thank you all. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
