you should not persist hibernate entities between requests,
a call was loaded from db, and put into list,
after that it was stored in mem and session closed
on next request you use that ol object and
when a lazy loaded property "usr" was being initialized by
hibernate, it failed.
the doSearch shold be called inside a render request, not inside
acton req and persisted.
you should persist a flag
@Persist private boolean isSearch;
String onSuccess() {
isSearch=true;
return null;
}
public List<Call> getCalls() {
if(isSearch) return session.createQuery("from Call").list();
return new ArrayList<Call>();
}
if you use grid,
I have something for it:
