First of all LoginWindow and MainMenuWindow are actually Panels (com.gwtext.client.widgets.Panel).
The Exception accurs when the second panel is created, Doesnt matter what the order is.
What I am looking to achive, is moving from the login screen to the mainmenu screen.
How do I do this..?
do I redirect the url? do I change panels?
How do I associate a GWT window to a certain URL? except for using the entry point..
I Dont need Help, But thanks anyways.
I Have found the Problem:
It seems the problem is only on the Panel Class, And when using panels that extends that class, Any one of the meny class`s seem to work good.
I dont fully under stand the reason, but I this seems to be the solution.
