When I call session.Restore(obj) it is reloading the objects from the database (at least that is what the sql trace shows) I want to be able to reload but avoid going to the database as the entities can be very large.
Yes I want to set all the entities in a session to the state they were in when begin transaction was called. I need to be able to create restore points.
