that thing in your BaseEngine will not work. I forgot to tell you why are you getting this exception. When you load an object, then close session, and then try to read some property that have not been intialized the first time, then you got that exception. It's because hibernate's session is closed or disconnected. If you are in a deathline, you can put "lazy=false" in all your mapping classes and in all your collections mappings. It'will work like a charm. But it's not a good decision if you care about performance.
