PrivateOwned dont work in Embeddable class [message #626910]

Hello, this is my first post in the forum. I have a problem with the annotation @ PrivateOwned with @ Embeddable. My classes:

@ Entity
public class A (
      @ Embedded
      B b;
)

@ Embeddable
public class B (
      @ OneToMany (mappedBy = "a", cascade = CascadeType.ALL)
      @ PrivateOwned
       List <C> lc;
)

The above example, at the time of deletion, the records of the table represented by the class "C" are not excluded and not disconnected. If I add the contents of class "B" directly in "A" works like a charm.

I tried to modify the mapping "OneToMany" to mappedBy = "b" but an error occurs.

Does anyone know tell me if the PrivatedOwned work with Embeddable or whether this is a bug. I'm using the eclipselink-2.1.1.v20100817-r8050 version.

thx a lot.

Hello,

I don't see anything wrong with your mappings. The relationship from C needs to be to A since B does not have any identity. Private ownership is expected to work on any relationship field by causing the referenced entity to be deleted when the entity is dereferenced from the relationship.

Can you show the code you are having problems with and describe what you mean by add the contents of class "B" directly in "A"?

Best Regards,
Chris

thx for reply.

@Entity
public class A {

      @OneToMany (mappedBy="a",cascade=CascadeType.ALL)
      @PrivateOwned
       List <C> lc;

}

The above example works like a charm. Surprised
