Hi Stevko! The class "Torneo", it's definite:
@PersistenceCapable(identityType=IdentityType.APPLICATION,detachable="true")
public class Torneo implements Serializable {
/*
* @author Lisandro della Croce
*/
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String nombre;
......
@Persistent(defaultFetchGroup = "true")
private List<Equipo> equiposTorneo;
Is correct?
Regards
