I have my doubt here. * basically, you want to combine two commands (speed and position) with the help of dynamic properties which sounds kind of bad. * if you have a system state change you most-likely reconfigure your hole network anyway. * dynamic properties make it incredible complex to test your components * there is no logging if you change properties from vizkit * we have no tooling allowing to reconfigure tasks dynamically according to log files
For me the hole dynamic property thing is a really bad idea and not needed in 99% of the cases. Alex -- Dipl.-Ing.
