Hi! Torneo dbTorneo = pm.makePersistent(unTorneo); dbTorneo.agregarEquipo(unEquipo); .... Following this step one does not add in the base an object "unEquipo" I had to add immediately afterwards to these lines immediately: pm.makePersistentAll(dbTorneo)
This way if persite the objects of the collection, which seems to me mas logically of being necessary the makePersistent. Some suggestion? Thanks Regards On Jan 3, 4:02 pm, "A.
