Hello

I'm mapping a legacy database with hibernate 3.1. I have an issue with a convention on the legacy database mapping (witch is also OR mapped manually by a legacy application) and I can't find a good way make hibernate 'live' with it.

The problem is the the legacy ORM uses -1 to mark an non established many-to-one relationship.

I've allready patched hibernate to return null when it finds a -1 in a foreign key field. Is there any way I can do the oposite. i.e. make hibernate translate null to -1 in many-to-one associations when persisting the entity? (At first I've tried Interceptor but with no success as it's needed to pass over the typesfety of the setters)


Many thanks
