I think I might be having a problem with Apache Delta Spike. I have a parent entity which is already persisted and I am adding a new child to it. If I use the EntityRepository, I get a duplicate key problem on insert because it must think the parent is not yet persisted:
[code] entityRepository.save(parent); // this throws a duplicate key exception
entityManager.merge(parent); // this works [/code]
The funny thing is, is that I checked the source for CdiQueryInvocationContext, and it is doing the same exact thing I am doing, it checks if the parent has an identifier. If so, it calls merge instead of persist.
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry 'user-1' for key 'User_Environment'
Any ideas? For the time-being, I'll use entityManager, but that defeats the purpose.
Thanks,
Walter
