Howdy ya'll, I posted this Friday but no one's biting so far... Has anyone had problems with session-scoped ActionForms being null after (de)Serialization (context restart). I have confirmed that running myForm.reset(...) on my ActionForm after restart throws a NullPointerException via debugging filter I've got set up.
