So.. if I think I understand right... Basically, I think the issue boils down to this - the object you have in session may, or may not be in the Transfer cache.
So it may not be updated when the TO in the Transfer cache gets updated. This is where I would just store the ID of the object you reference in session, and let Transfer manage the session. Does that work? Or did I miss the point of this?
