I keep getting a StackOverflowException when trying to save a region object. Doesn't matter if lazy is true or false. or if an inregion is provided or not. I've seen similar post but no replies. Any suggestions or help is appriciated.

NHibernate version:1.0.2

Mapping documents:

Code between sessionFactory.openSession() and session.close():
s.Save(obj);

It's probably not in the NHibernate code, but the getters and setters of your object.

I've seen this when I have the getter/setter referring to itself rather than the internal field being used for NHibernate. (oops!)

Check your class for this one.

Symon.

Found the problem. My base classes were OK. The problem involved a generics issue. Anyway unrelated to NHibernate
