Yes. Hibernate sessions re cheap, however, though it would be nice to
keep some of the session validity a teensy bit longer to get more
caching value out of the L1 cache. But what you say is true,
and .merge() is probably what you need here.

Hi Lasitha,
Thanks for the link, but what's the conclusion? Tapestry-hibernate
has to be
updated to close the session? there seems no decision in that
thread. I use
now merge which get rid of the problem so far. I'm new to this T5 form
handling, if I understand correctly: onActivate the session was opened
because a object is retrieved, then automatically close. onSuccess
another
session was opened because of call to update/merge, am I right here?

Hi,
I have code like following, but it generate an exception when form
submits,

instance,

hints on how to fix this? thanks.

Illegal attempt to associate a collection with two open sessions
@Persist
private Usr usr;
@Inject
private Session _session;
public Class onActivate(Long id) {
usr = (Usr)_session.get(Usr.class, id);
}
String onSuccess() {
_session.saveOrUpdate(usr);
return null;
}
