Boerries,
What you're attempting to do are self relations and these are not
supported in Castor. You're relating an object of type keyword to an
object of type keyword. In certain models, Castor can handle very simple
forms of this type of relation. However, it is not a supported feature.
As you've discovered this type of relation breaks down very quickly.
