Andrus Adamchik commented on CAY-2047:
--------------------------------------
Now that I think of it, such mapping is really wrong, as FK does not really
guarantee that it will resolve to an expected subclass. But perhaps the Modeler
can be more verbose about it...
> Relationship mapping with target inheritance
> ---------------------------------------------
>
> Key: CAY-2047
> URL: https://issues.apache.org/jira/browse/CAY-2047
> Project: Cayenne
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Andrus Adamchik
> Assignee: Andrus Adamchik
>
> Consider the inheritance mapping:
> DB_A
> ObjSuperA
> ObjectSubA extends ObjectSuperA
> DB_B
> ObjB
> There are 2 to-one relationships from DB_B to DB_A based on 2 foreign keys.
> Modeler ObjRelationship dialog fails on attempt to map ObjB -> ObjectSubA (a
> subclass) relationship. It automatically selects a superclass instead.
