T5: how to use a detached hibernate object in a form?

[Angelo Chen]

Hi,

I have code like following, but it generate an exception when form submits,
i thought there is only one Session open and usr is a detached instance, any
hints on how to fix this? thanks.

A.C.

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;
}
