Okay. Last question (and I promise to write up a post on this).. When I have seen session.Persist() mentioned before it's been stated that it's not guaranteed that it will provide an id. Is this correct? Are there any conditions that would cause this to occur because in my very limited testing it seems I can retrieve the Id after it's called.
