Hi! I have a problem with persist the class "Fecha". The class
"Fecha":
The following classes are:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Fecha implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String nombre;
@Persistent
private Date fechaIni;
@Persistent
private Date fechaFin;
@Persistent(defaultFetchGroup = "true")
List<Partido> partidos;
private Long id2;
private Long kind;
....
The class RegFechaUsuario:
public class RegFechaUsuario implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private int puntos;
@Persistent
private Long idUsuarioFecha;
@Persistent
private Long idFechaOriginal;
@Persistent
private Fecha fechaRegUsuario;
......
The method where the mistake happens:
Transaction tx = pm.currentTransaction();
try {
tx.begin();
//at makePersistent is the exception
pm.makePersistentAll(regFechaUsuario);
tx.commit();
} finally {
The exception:
Problem accessing /Prode/JugarFecha.action. Reason:
oid is not instanceof javax.jdo.identity.ObjectIdentity
Caused by:
java.lang.ClassCastException: oid is not instanceof
javax.jdo.identity.ObjectIdentity
