Tip for bone dynamic and actions

[Hamedss]

Hi. I recently faced a problem and trying to post in general forum but I discover the answer so I share it here.
Hope it help somebody.
We have a simple rig of 3 bones: bone A/bone B that B is parented to A and third bone S for smart action. If you activate bone dynamic like angle dynamic for B and in and create a Smart action for S so it rotates the B ,the bone dynamic will not work any more.
So you should put an extra bone D between A and B
Parenting : B to D to A
And rotation of D will turn B but the bone dynamic works well.
