I'm using the Google AppEngine, with Java. When I use some datastore
features, I'm getting an error message:
"Objeto con id "model.fe...@cf17c3" es manejado por otro
ObjectManager".
The code:
public void crearPartido(String nombre1, String nombre2,Date
fecha,Fecha fechaAgreg) {
//JDOHelper.getPersistenceManager(obj);
PersistenceManager pm2 = PMF.get().getPersistenceManager();
Transaction tx = pm2.currentTransaction();
try {
tx.begin();
Equipo eq1= new Equipo(nombre1, "", "");
Equipo eq2=new Equipo(nombre2,"","");
Partido par1=new Partido("", "", eq1,eq2, fecha);
fechaAgreg.agregarPartido(par1);
pm2.makePersistent(fechaAgreg);
} finally {
tx.commit();
pm2.close();
if (tx.isActive()) {
tx.rollback();
}
}
}
And the persistent manager class:
public final class PMF {
private static PersistenceManagerFactory pmfInstance = null;
public static PersistenceManagerFactory get() {
if ((pmfInstance == null )||(pmfInstance.isClosed())){
pmfInstance = JDOHelper.
getPersistenceManagerFactory("transactions-optional");
}
return pmfInstance;
}
}
Regards!
