-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
still having problems with my join on constant, however found the bug in my merge() usage. Problem was I loaded Objects D in class A and wanted to persist in B. In class A and B I had the statement: emf = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME); em = emf.createEntityManager(); This was causing in openjpa the error. (though not in eclipselink :) ) Passing reference to Entitymanager from Class A to B solved this problem. Greetings, Adam -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlEKrxIACgkQefEEI87R1DeYwgCghIQVQwihpeDLkXzS0chLVf4k a8MAoJrpCNDaB8cv7qEbh5xBpdMnGJTO =7waa -----END PGP SIGNATURE-----
