Hi Martin, I'm new to wicket. Could this have something to do with wicket trying to restore a page from serialized data. If one of the objects on your page can not be serialized you will get an error when wicket tries to restore the page. I think you might see this when the back button is pressed. I think using a detachable model is one option if you use a 3rd party object that isn't serializable.. If you wrote the object you can make is serializable. Then again I could be all wrong.
