Forcing a different operations order on persited entity [message #1742949]

I have an already persisted entity with EclipseLink. I perform some changes on it that cause a constraint violation because of the inserting before updating.

As stated in the documentation the operations are performed in the following order Insert/Update/Delete. There is a method that permits for the delete to be executed first but I can't find any solution to make an update execute before insert. Is there some workaround so I could maybe redefine the order like Delete/Update/Insert?

Why would inserting before the update cause a constraint violation? Generally something has to exist in the database before any existing rows can be updated to reference them, so the insert/update order is one that is calculated on an entity by entity basis. If there is a constraint being hit, is it something that you have mapped in your entity, or is it due to a circular mapping?
