Control4 API Observations

I've been pondering the issue regarding proxybindingid in connections, whenever I followed other examples mine would never work.

However I always specified 5001 first in the connection list, turns out, that Composer doesnt like this. You must specify them in NUMERICAL order. So inputs (1000-1999) then outputs (2000-2999) then the AVSwitch (5001) if you put that one first, all hell breaks lose
