Tag grouping at MDG element with tags from generalizations

[Jacob Vos]

I want to apply tag grouping in an MDG, but my situations seems to be too complex. This is my situation:

1. Metaclass Class
2. Metaclass Class
3. Stereotype MIM::Objecttype
4. Stereotype MyMDG::Objecttype (extension to 1)
5. Stereotype MyMDG::ObjecttypePlus (extension to 2, generalization to 3 and 4)

Tags are defined at:
3. MIM::Objecttype (not be me)
4. MyMDG::Objecttype

Now for 5 (myMDG::ObjecttypePlus), I want to have two groups of tags: MIM and MyMDG. For this in Class 2 I defined tagGroups and tagGroupings. When using the MDG, the tag groupings are shown, but the tags aren't grouped in it. Probably this is because the tags aren't defined in 5, but in 3 and 4.

Can this be solved, and if so: how?

I already tried to define the same tagGroups and tagGroupings in Class 1 and in MIM:Objecttype, but without result.

SOLVED!

I did one thing wrong in _tagGroupings: instead of the '=' sign I used the ':' sign...

Works great now!
