Hello,

I have a table with a generated Id (mapped as Id in Hibernate) and a logical Key (a normal property with a unique index in database).

If I use saveOrUpdate, it looks for the Id, and if its not in table, it uses save to save the object. So it can happen, that it tries to generate a new row, but fails, because of the logical key.

I would like to change the behavior so it looks for the logical key, instead of the Id, to determine if it should save or update.

How can I do this?

Bye Michael
