I've got a Master-Detail edit page where the user can add and

If I delete a detail record and then add a new one with the same
unique key and save, it causes a constraint violation in the
database. Looking at the generated SQL, it is executing the INSERT
before the DELETE, even though the delete happened first. Why is
this happening?
What database are you using? Some databases can defer asserting the
constraints until commit. That's probably what you want.
Alternatively, there is a WO api that allows you to manually order
the SQL operations.
