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.
> Exception using @Strategy in @MappedSuperclass or @Embeddable classes

> Key: OPENJPA-1570
> URL: https://issues.apache.org/jira/browse/OPENJPA-1570
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.0.0-beta2
> Environment: Ubuntu 9.10, Maven 2.2.1, Spring 3.0.1
> Reporter: Oliver Ringel
> Attachments: openjpa1570.tar

> 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.
