Subject [jira] Created: (OPENJPA-1570) Exception using @Strategy in @MappedSuperclass @Embeddable classes
Date Sat, 13 Mar 2010 14:13:27 GMT
Exception using @Strategy in @MappedSuperclass @Embeddable classes

                 Key: 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

the same exception occurs if you add the @Strategy annotation on a field of an @Embeddable
or @MappedSuperclass (not part of an @ElementCollection).
The attached 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.Table(name = "TESTENTITY")
public class TestEntity extends TestEntityBase {

public abstract class TestEntityBase {
    @Column(name = "TESTENUMSIMPLE")
    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.
