Having a bit of a problem here with a unique constraint. I have a collection that references the following table:

pkid_associate_region
fkid_associate
fkid_region
value

The table has a unique constraint on (fkid_associate, fkid_region). In other words, each associate record can have only 1 value per region.

However, if the user deletes a record and then creates a new one in the same region that was deleted, it violates the unique constraint because it tries to perform the SQL inserts before the deletes.

Is there any way to force Hibernate to process the deletes from the collection before the inserts?

I'm calling saveOrUpdate() on the parent object which updates/inserts/deletes all of the child objects in the same transaction.

Hibernate version: 2.1.7c, 24.11.2004
