can you show the parent class, with the field for for the Equipo child? It will no doubt have @Persistence annotations too... -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Re: Persist child - Problem
Perhaps Equipo is not properly linked to Fetcha?
something like:
@Persistent
private Equipo myEquipo;
public setEquipo( Equipo e ) { this.myEquipo = e; };

[appengine-java] Re: Persist child - Problem
Thanks andrew! My class Equipo has @persistence capable and
and serializable... The code:
import java.io.Serializable;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
import com.google.appengine.api.datastore.Key;
@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
public class Equipo implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String nombre;
@Persistent
private String imagen;
I'm not understand because it not pesist in the datastore.
Regards!

[appengine-java] Re: Persist child - Problem
Is the child annotated as @persistence capable? Is it serializable? It also depends on the type of keys used and key generator strategy. Show us the code defining each class and we'll let you know. Quizas asi te ayudamos a poner tu equipo en primera división! :-) -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
