Hi.
I got such error today Long time ago i had similar problem but with
ClassCastException while deserialization. It was because i kept
references from one page inside another. Nowdays i dont have such
navigation, im using:
RequestCycle.get().setResponsePage(xxxPage.class)
Any ideas ? Hints ? Unfortunetly i dont know how to reproduce it. I got
it only one time ;/
