A very short hint from my side: that exception means this object is not in the session anymore. You can easily reapply it to the session by calling
session.update(object) If you are sure that your object has not changed since it was last in the session, you can call: session.lock(object, LockMode.NONE); regards, Martin On 8/31/05, Werner Punz <[EMAIL PROTECTED]> wrote: > I think before giving a short answer...
