Hi,
I hope everyone had a good Christmas.
During processing models and entities I stumbled upon a situation where I get
an unexpected result. Basically I have an entity Parent with a subclass Child
using single-table inheritance. Then I have another entity Gift that has a
relation Parent <-->> Gift. Both relationships are marked as class attributes
so Parent./Child.gifts() and Gift.presentee() return the correct objects.
Now I am processing the corresponding EOModel objects and when I have the model
for Child doing:
EORelationship rel = childModel.relationshipNamed("gifts");
EORelationship inverseRelationship = rel.inverseRelationship();
leaves inverseRelationship with a null value though it should have been set to
the presentee-relationship. Digging into EORelationship. inverseRelationship()
reveals that it compares the entity (Child in this case) with the destination
entities from Gift. Too bad that it resolves to Parent so EOF simply says that
there is no matching inverse. Seems as a bug to me. It should check for entity
equality and then equality with any subclass if present. Any thoughts?
I found the method EORelationship.anyInverseRelationship() that returns an
internal inverse but of course that is not really useful when calling
valueForKey on an object with the returned key name later on.
