Deformation Composite Troubles

Hi there,

I’ve some troubles with rigging a character with the deformation composite. I’m trying to follow this guide: Community - Toon Boom Animation
The guide is I think from the pre Harmony 12 days, so things are a bit different. I don’t have everything ordered in groups, for example. But the chains should be the same.

Anyway, the trouble comes when I try to match the output value between de “Deformation Composite”(A) and the “Deformation Composite Kinematic”(B). I set the settings in B to "Use Parent Composite’s Connected Element Exposure. B should now copy the value for linking the the correct chai from A, as I connected B as a child to A. . Still, it doesn’t seem to copy the value.

Am I missing something here?

I added an attachment for clarity.
