Hi all,
i have a support case with apple, where they confirm that there is a bug
with making recursive n:m relations between abstract base classes in
combination with vertical inheritance. Nothingtheless it works with
horizontal inheritance.
For those who are interested: i have a sample project i would share with
you, but i dont want to spam it to the list.
regards
Wolfram
