Hi! I have a problem with active transaction.When I try to guard in
the datastore, says:
"Object with id "com.google.appengine.api.datastore.Key:Torneo(1)/
Equipo(3)" is managed by a different Object Manager".
Disegn:
A Torneo has relation one to many Equipo
A Fecha has relation one to many Partido
The method:
private static PersistenceManager pm =
PMF.get().getPersistenceManager();
//pm is a singleton
public void crearPartido(Long idEqLocal, Long idEqVisitante, Date
fecha,
Fecha fechaAgreg, String resultado, String
hora,Long idTorneo){
PersistenceManager pm =
JDOHelper.getPersistenceManager(fechaAgreg);
//or Transaction tx = pm.currentTransaction();
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();
}
}
And the method crearPartido is called for:
public String execute() throws Exception {
ControladorFecha cF = new ControladorFecha();
Fecha fechaSel = cF.devolverFecha(fecha, torParam);
ControladorPartido cP= new ControladorPartido();
cP.crearPartido(idEquipoLocal, idEquipoVisitante,
fechaPartido,fechaSel,resultado,hora,torParam);
return SUCCESS;
}
Thr method "devolverFecha":
private static PersistenceManager pm =
PMF.get().getPersistenceManager();
//pm is a singleton
public Fecha devolverFecha(Long idFecha, Long torneo) {
Transaction tx = pm.currentTransaction();
try {
tx.begin();
Key k2 = new
KeyFactory.Builder(Torneo.class.getSimpleName(),
torneo).addChild(Fecha.class.getSimpleName(), idFecha)
.getKey();
Fecha f = pm.getObjectById(Fecha.class, k2);
tx.commit();
return f;
} finally {
if (tx.isActive()) {
tx.rollback();
}
//pm.close();
}
}
Regards!
