for sure, but if i persist an object in the http session, i've got the same object again after page reload? So i should be able to save it in the hibernate session because it is the same Object?
e.g. first page load -> get ObjectA from DB -> save ObjectA in http-Session second page load -> get ObjectA from http-Session -> save ObjectA in DB but this throws an "a different object with the same identifier value was already associated with the session:" Exception. So according to Jose i don't get the right Object (that is bound to the hibernate-session) from the http-session!? -----Ursprüngliche Nachricht----- Von: Ulrich Stärk [mailto:u...@spielviel.de] Gesendet: Montag, 8.
