Editor for hierarchy

Igor Karpov wrote:

Assume that there is a small concept hierarchy

A

+-B

+-C

A has a 'integer child concept property' magicValue, and B has magicValue=1, C has magicValue=2

Is it possible to define an editor only for concept A that will (magically) display this magicValue, without defining editors for every inherited concept like B and C? I've tried that but mps says 'no editor found'

Thank you for feedback.
