I have an jdo enabled object that has an primary key id generated by a mysql auto incremented integer. Therefore i use the "org.apache.ojb.broker.util.sequence.SequenceManagerMySQLImpl" SequenceManager. I tried to disable the cache by setting: lFactory.setIgnoreCache( true); lFactory is the PersistenceManagerFactory.
Then i executed the following code: (lA1 and lA2 are two valid objects)
lManager.currentTransaction().begin();
lManager.makePersistent( lA1);
lManager.currentTransaction().commit();
lManager.currentTransaction().begin();
(*) lManager.makePersistent( lA2);
lManager.currentTransaction().commit();
the following exeption is throws at (*) :
javax.jdo.JDOUserException: Object exists. Instance with the same primary key is already in the PersistenceManager cache.
