> one-to-many relation with not-null attribute on key element is throwing below error when I run the hbm2java tool. I have a base class with a joined-subclass and the joined subclass has one-to-many relationship with another class. The one-to-many uses a list. When I specify not-null attribute on the key element in the relationship I get the below error. If I remove it I don't get this error. If I let the key stay not-null, during run time persistence fails. So I had to revert the mapping file at runtime for the persistence to go fine. It is only the tool that is misbehaving.
