Igor Vaynberg resolved WICKET-2697.
-----------------------------------
Resolution: Won't Fix
Assignee: Igor Vaynberg
those classes are not meant to be serializable or for you to hold them in
session.
even if we did make the listenerset serializable you would still have to make
sure that every listener inside is also, this would cascade down to everything
else.
> org.apache.wicket.util.listener.ChangeListenerSet should be serializable
