Miro,
Your use of the ProxyFactory looks fine (although you could also do the
Spring configuration in your application context and use @SpringBean to
inject your proxy in a Wicket-safe way).
Anyway ... is ReassignGrantsOfficerPage Serializable? Do you want it to be
serialised in the page store?
Also, since CompoundPropertyModel is an IChainingModel, you can try try
something like:
class MyProxyModel extends LoadableDetachableModel{
protected Object load(){
return getProxy();
}
}
... and ...
public ReassignGrantsOfficerForm() {
super("reassignGrantsOfficerForm",myProxyModelInstance);
...
}
so your CompoundPropertyModel is not holding on to an instance of your proxy
(which, incidentally, is fixed when your form's constructor is run - ie it
is not dynamic/evaluated per render).
I'd be interested to know if that's what you needed as the code provided may
not tell your whole story.
