Embeddables don't inherit their 'isolation' status [message #559026]

I am using EclipseLink 2.1.1.

When using the sharedCacheMode ENABLE_SELECTIVE, I have a problem with embeddables: if no @Cacheble(true) annotation has been defined on the entity that contains the embeddable, it seems that the descriptor of the embeddable has the 'isIsolated' property FALSE. If that embeddable contains a ManyToOne reference to another entity that is not cached, a DescriptorExcpetion is thrown, saying that an shared object cannot have a reference to an isolated one. In case of an embeddable, I would expect the embeddable's 'isIsolated' state to be the same as the entity that contains it (in this case TRUE).

A simple example:

@Entity(name="Person")
@Cacheable(false)
public class Person {
@Embedded
private Address address;
}

@Embeddable
public class Address {
@ManyToOne
private City city;
}

@Entity
@Cacheable(false)
public class City {
}

Hello,

Bug 304868 exists for this problem, and includes a workaround of using a customizer to correct the setting in the embeddable's descriptor. The embeddable's descriptor should be a special case as embeddable objects are not cached anyway.

Best Regards,
Chris

Thanks for your reply. I'll check the bug and use the workaround meanwhile.
