Subject Re: Validation and @PrePersist

Hi Hugi,

If validateForInsert() is being called before PrePersist, we have a
disconnect between the documentation and the behavior you are seeing:

"PrePersist: right before a new object is committed, inside
ObjectContext.commitChanges() and ObjectContext.commitChangesToParent()
(and prior to validateForInsert())."

What version of Cayenne are you using?  I wonder if something has changed
or if the documentation is just wrong.
