Hi
The error occur in OpenJPA 2.0.2 but don't occur in OpenJPA 2.1.0 and 2.2.0.
I made the minimum test classes to be errored for OpenJPA2.0.2 and Oracle
10g.
-----
package
org.apache.openjpa.persistence.annotations.common.apps.annotApp.annotype;
import javax.persistence.*;
@Entity
public class MinEmbeddableSuperSub extends MinEmbeddableSuper {
@ManyToOne
private MinEmbeddableSuper sup;
}
-----
package
org.apache.openjpa.persistence.annotations.common.apps.annotApp.annotype;
import javax.persistence.*;
@MappedSuperclass
public class MinEmbeddableSuper {
@Version
private int version;
}
-----
If you persist the entity class in Oracle, you get following error.
Attempt to set column "MinEmbeddableSuperSub.version" to two different
values: (class java.lang.Integer)"0", (class java.lang.Integer)"1" This can
occur when you fail to set both sides of a two-sided relation between
objects, or when you map different fields to the same column, but you do not
keep the values of these fields in synch.
thank you
