Hi *,
I've just done some refactoring in my project and am now finding that my
PlaceHistoryHandler is no longer able to trigger a default Place. I'm
following the default procedure as described in the GWT online
documentation as you can see in the source code at the end of the mail.
After some debugging, I have detected that the listeners for the
PlaceController are not in place early enough. When doing any navigation
activites in the menu later, everything works fine and the
ActivityManager and PlaceHistoryHandler are both showing up in the
listener queue.
The MVPManagement is activated in an event listener that is triggered
after the app has retrieved the user profile after an RMI call.
Any help or advice is greatly appreciated :)
Ralf
