Subject [jira] Updated: (OPENJPA-1570) Exception using @Strategy in @MappedSuperclass or @Embeddable classes
Date Sat, 13 Mar 2010 14:40:27 GMT

Oliver Ringel updated OPENJPA-1570:
-----------------------------------

    Description: 
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.
