@Embeddable Primary Key with @ManyToOne Relation

[bendis]

Hi!

I have an entity bean with composite primary key, something like:

@Entity
class EntityBean {
 @Embeddable
 static class PK {
 String id1;
 String id2;
 }

 @EmebeddedId
 PK pk;

 @Column(nullable = false)
 int value;
}

and there are no problems, everything works and when I check the database, the primary key is composed of both 'id1' and 'id2'... But now I change 'id2' to be a foreign key of some other entity, let's say 'OtherEntity':

@Entity
class EntityBean {
 @Embeddable
 static class PK {
 String id1;
 @ManyToOne
 OtherEntity oe;
 }

 @EmebeddedId
 PK pk;

 @Column(nullable = false)
 int value;
}

@Entity
class OtherEntity {
 @Id
 String id;
}

And when I check the database, the primary key of EntityBean is now composed only from 'id1'! Shouldn't 'otherentity_id' (the foreign key column in EntityBean table) be also part of the primary key?

Is this a bug or correct behavior?

Thanks,
Bendis
