This was a secondary effect caused by a Model that could not be successfully serialized. In the model, one of the members held a non-serializable object. I set the member to null in the onDetach() method, but apparently onDetach() was not being called. I have since changed the member so that it is declared as transient, since all I was doing in onDetach() is setting it to null. I am investigating why onDetach() was not called, but have not yet come up with an answer.
Thanks,

Everyone,
I am getting the following error whenever I try to hit a certain page in my webapp. The error can be reproduced and happens every time I try to access the page. I have not yet been successful in creating a small non-trivial test app that will display this behaviour. Any thoughts would be appreciated.
Thanks,
