I’m out of the office at the moment, so can’t look at the code, but from memory MX does not treat Boundary objects as ‘real’ objects, as they are mostly used on diagrams just a boxes, to make things look neat.
I have a feeling that in Archimate 3 this may not be true. Is the Archimate ‘Group’ idea based on the Sparx ‘boundary’ ? If so, than maybe I need to change how this works.
