Hi,

I have a class

A

and class B

B : A

A has normall class mapping
B has joined-sublcass mapping..

Everything goes OK - I can create A, create B, update A, update B ...

The urgent problem is when I load A and I create B basing on it for example making B something = (B)A;

When I want to update B, it says that there is no row with specified id,
I cant create A, it already exists, update A because B is not created then, create B because something else occurs.


IMPORTANT: There are two tables in database related one to one with the same primary key

Maybe if we could see your mappings we might be able to provide more info. It sounds like a mapping issue.
