[jira] Created: (OPENJPA-689) @ID define in super class
@ID define in super class
-------------------------
Key: OPENJPA-689
URL: https://issues.apache.org/jira/browse/OPENJPA-689
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.1.0
Reporter: wilesun
Fix For: 1.1.1
our entities have share super class,the class has one field define the entity id,so we define the class as mappedsuperclass
when we work with hibernate JPA,it work fine.
but migrate to openjpa,the PCEnhancer don't assign other entity has ID class,so the query sql is incorrect.
example:
@MappedSuperclass
public EntityBase {
@Id
@Column(name="ID")
private String id;
}
@Entity
public B extends EntityBase {
}
@Entity
public C extends EntityBase {
}
Object o = em.find(B.class, "111");
the sql list:
select * from A where id=?
select * from B where id=?

[jira] Commented: (OPENJPA-689) @ID define in super class

Pinaki Poddar commented on OPENJPA-689:
---------------------------------------
Description of this issue is not clear enough.
Can you please elaborate further what is the problem being encountered when entities inherit from a @MappedSuperclass?
It may be worthwhile to discuss any potential issue in the OpenJPA user group before creating a JIRA issue.

Fernando commented on OPENJPA-689:
----------------------------------
I am doing this right now. Did you add the EntityBase to the persistence.xml classes list? Since it has to enhance the mappedSuperclass too.
