Hi!Marcus, now I use your pattern for transactions:
The code of the method:
public void crearPartido(Long idEqLocal, Long idEqVisitante, Date
fecha,
Fecha fechaAgreg, String resultado, String hora,Long
idTorneo){
PersistenceManager pm =
JDOHelper.getPersistenceManager(fechaAgreg);
Transaction tx = pm.currentTransaction();
try {
tx.begin();
Partido par1 = null;
ControladorTorneo cT= new ControladorTorneo();
par1 = new Partido(null, new Resultado(),
cT.devolverEquipo( idTorneo,idEqLocal),
cT.devolverEquipo(idTorneo,idEqVisitante), fecha, hora);
/*In mode debug, is here below where accedes for the
block finally(with error) */
fechaAgreg.agregarPartido(par1);
pm.makePersistent(fechaAgreg);
tx.commit();
} finally {
if (tx != null && tx.isActive())
tx.rollback();
pm.close();
}
}
But now, the error is:
"Object with id "com.google.appengine.api.datastore.Key:Torneo(1)/
Equipo(3)" is managed by a different Object Manager".
I try also changed in the code:
"PersistenceManager pm = getPersistenceManager();
For:
"PersistenceManager pm =
JDOHelper.getPersistenceManager(fechaAgreg);"(But mistake is the one
that already I enunciated).
