Normal Code Generation is fine :-)
Wheres the NHibernate Code generation does nothing.
No error visible. No Code generated...
Currently, NHibernate code can be generated only from ERD diagram, because it natively supports information about nullability, type size, etc.
Maybe I could add some warning about it to the application. In one of next versions, I could also prepare a source code template for NHibernate code generation from a class diagram.
