is ReassignGrantsOfficerPage Serializable? Do you want it to be serialised in
the page store?
Yes ReassignGrantsOfficerPage is Serializable because all wicket
components are serializable, yes.
ReassignGrantsOfficerDTO represents the user entered form values and no
lookup values so I dont want to use detachable model , I am just
wrapping my form model with additonal meta information needed by my
service layer,so please tell me will there be any problem with cglib proxy
serialization ? like can we have cglib generated proxies in wicket pages
?
