RE: ModalWindow detach/serialize crashes wicket app
Clint, Pedro, Thank you both for your replies. Based on your comments, and from looking at a heap dump, I am thinking the problem may stem from an inner class created by our app's wicket Session. I have made the inner class static, so that it will no longer hold a reference to the Session. The inner class is a model which loads a reference to a User object. Any hints on how to reproduce the problem, so I can prove it? I'm not clear on what triggers the serialization process that causes the error to be thrown. RUSSELL E.

Do you have a propetymodel with the session as its object?
