Hi, In my application i have a requirement that eventhough i change the values of persistent objects available in the session directly using getter and setter methods i have to save only the objects on which the EntityManager.persist() is invoked explicitly. To resolve this problem we maintain 2 managers one for read and another for write. I detach the object from the read entity manager and merge the same with the write entity manager before calling a persist(). The problem here is that OpenJPA is generating an insert query to save the persistent object eventhough it exists in the table. This is giving me an Unique constraint violated error. Is there anyway to tell OpenJPA to check for the existence of record with same primary key before persisting. Any help is highly appreciated.
