i've two shape classes A and B and the instances A1, B1, B2.
The connections A1-B1 and A1-B2 should be allowed, but then a 2nd connection A1-B1 can't be forbidden with the IsTrgNeighbourAccepted(className) function.
Is there a solution for this problem?
I'm afraid this functionality is not provided by wxSF for now. Please, make new Feature Request record and I'll look at it as soon as possible.
