Hi!Cyrille I add a primary key in my child class:
@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
public class RegFechaUsuario extends Fecha {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private int puntos;
@Persistent
private Long idUsuarioFecha;
@Persistent
private Long idFechaOriginal;
And the exception is:
Error in meta-data for model.RegFechaUsuario: More than one
primary key field.
Caused by:
Error in meta-data for model.RegFechaUsuario: More than one primary
key field.
org.datanucleus.store.appengine.MetaDataValidator
$DatastoreMetaDataException: Error in meta-data for
model.RegFechaUsuario: More than one primary key field.
