Hi, I've postet a question in this thread (http://groups.google.de/group/ nhusers/browse_thread/thread/643f89626633c2c8/431cd21218c3233e) and got a very good hint for events/listeners.
I've implemented a PreUpdateEventListener which fires when I try to update my business objects. I can access to the argument of the type "PreUpdateEvent" which has a "OldState" property. This shall contain my object as it was before I've updated my object, but it is always nothing/null. I've tried to handle my sessions in two different ways: Closing my session after each transaction or leave it open while my application is open. But there is no difference: OldState is always null. Do I have to take care of something else so I can access my oldstate?
