I'm experiencing another problem related to proxied class. We've implemented session-per-request approach for using NHibernate in ASP.NET code. When I have an NH object loaded from session1 (the object turns out to be a proxy), and make changes to it in session2 and call session.SaveOrUpdateCopy(object), then I get the exception below from NHibernate. If I remove the proxy from the mapping, then all works fine. Can some please help?
