I'm upgrading from Wicket 1.2.4 to 1.2.6 and there's obviously a change I'm
not able to find concerning the session (or...who knows?)
I've got a simple pair of pages, one for viewing a list of entity beans
(EJB3) and one for editing a chosen entity from the list page. I'm
comparing it to dozens of pages I've built like this in the past in previous
versions of Wicket and I just can't figure out why I keep getting this
exception:

I've tried implementing Serializable all over the place but it doesn't
help...and comparing this to apps I've built in the past in previous
versions of Wicket, this is "correct". I can pull up the ViewPilots page
just fine but if I even add a reference to the EditPilot page (i.e.
setResponsePage(new EditPilot())), then that page also throws the same
exception.
I'm on Ubuntu 7.10 and using Glassfish v2 as the container...but have
replicated the issue on Winxp and Vista. As you can see from the error,
everything is being developed in Netbeans.
What's the obvious trivial detail I'm forgetting? :)
Thanks!
