Visual paradigm: nested collaborations

I'm trying to create nested collaboration, just like that: enter image description here

But, in fact, Collaboration 2 isn't sub-node of Collaboration 1: enter image description here

So, say, when I drag first one (bigger), second one stays on its place. I have to select both items (Collaboration 1 and Collaboration 2) and then drag. And similar issues, which are annoying.

I tried many things to get what I need, but it seems impossible. Am I doing/understanding something wrong?

Solution

  • I found the solution: I need to use Model instead of Collaboration. Models can be nested. No idea why Collaborations couldn't though, but, it's not principal for me, so, problem is solved.
