Hi! I have a problem when I attempt persist an object,calling the next
code:
par1 = new Partido("ss", new Empate(),
eq1b, eq2b, fecha, hora);
//The class "Empate" extends of class "Resultado", and the error says:
"Received a child of type model.Empate for a field of type
model.Resultado. Unfortunately polymorphism in relationships is not
yet supported."
I read the documentation of google but he does not say anything,
neither he denies the support of the inheritance. It wanted to know if
really he supports.
The classes(Have I some mistake in the annotations for the
inheritance???):
@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
@Inheritance(customStrategy = "complete-table")
public class Resultado implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
private static final long serialVersionUID = 3039288063578312662L;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public static long getSerialversionuid() {
return serialVersionUID;
}
}
@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
@Entity
public class Empate extends Resultado implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
private static final long serialVersionUID = 3039288063578312662L;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public static long getSerialversionuid() {
return serialVersionUID;
}
}
Thanks and Regards
Lisandro
