Hi,
Since I migrated to Wicket 1.5 I get exceptions like this in my log file:

I understand that iBATIS uses CGLIB for lazy loading and CGLIB generates
classes that are not serializable, what I don’t understand is that why I
didn’t get these exceptions in 1.4? Is there a way to turn off page
serialization?
Thanks,
Zhubin
