Hibernate version: 3

Hi,

When I try to save a record with a constraint violation, an exception is thrown but Hibernate generates a primary key for this object (I am using HILO to generate the PK).

when the user changes the field that generates the constraint violation and tries to save the record, I get an exception

Quote:

Unexpected row count: 0 expected: 1

.
This is becouse hibernate wants to update the record, but it is never saved.

What is the best way to solve this?

thanks

One way, which may not be the best, would be to validate the data before saving it.

I know, but I want the DB to do the work :-)
