Oliver Ringel commented on OPENJPA-1570:
----------------------------------------

I not sure if you mean me with Charles, but I switched to the latest snapshot release from the apache snapshot repository and 
tested the attached test case and my project with the snapshot. Also I tested @Strategy with some combinations of @MappedSuperclass and 
@Embeddable.

@Strategy is working as expected now. Thanks very much for the quick help.

> An exception occurs if you add the @Strategy annotation on a field of an @Embeddable or @MappedSuperclass (not part of an @ElementCollection).
> The  patch OPENJPA-1556.patch does not fix the problem.
> <openjpa-2.0.0-beta2-rexportiert fatal user error> org.apache.openjpa.persistence.ArgumentException: Attempt to map "jpa.test.domain.TestEntityBase.testEnumSimple" failed: the owning entity is not mapped.
> To be more concrete. I try to change the default enum handling using an own EnumValueHandler. The Handler is working if you add
> the @Strategy to the @Entity. Adding @Strategy on a field in a @MappedSuperclass leads to the above exception.
> @javax.persistence.Entity
> @javax.persistence.Table(name = "TESTENTITY")
> public class TestEntity extends TestEntityBase {
> ...
> }
> @MappedSuperclass
> public abstract class TestEntityBase {
>     @Column(name = "TESTENUMSIMPLE")
>     @Enumerated(javax.persistence.EnumType.STRING)
>     @Strategy("jpa.test.domain.EnumStrategy")
>     private TestEnumSimple testEnumSimple;
> ...
> }
> You get the same Exception if you add the @Strategy to a @Embeddable and I also tried a own simple StringValueHandler with the same result.
