Enivob - your kind of missing the point. Its clear that it works with Active set to 1. But, what we want is Active set to 0 for all pieces. We want to allow the Impulse Activation to switch the Active (0's) to Active (1's) based on the impact of the object. The whole point here is to get Impulse Activation working with constraints. Not completely bypass the Impulse Activation Method.

I was having the exact same problem today. Enivob, your setup does seem to fix it. But, it also completely bypasses the Impulse activation. You are setting everything to active on the first frame.

What cruiserandmax and I are trying to do is have all packed pieces inactive until they are impacted, they would then turn active. And, also have working constraints. Right now I am unable to get impulse activation working with constraints. My guess is that the constraints are stopping the impulse activation from ever hitting its threshold to become active. Seems like an order of operation problem to me.
