This is the expected behavior :)
and it will remain this way.

Is this a 'trick' that you use to get around it or it this officially supported ? Like can we expect this trick to work in a few months / can we use it for new work.

By the way, the reason Isadora prevents you from creating closed loops of actors like this is to try to avoid allowing situations where users can accidentally program themselves into a corner with infinite loops. Once you know the workaround of tricking Isadora into thinking it's not a closed loop it's pretty easy to get around though.

Also, adding anything that makes it not a closed loop gets around this.

Thanks

Hi, 

I think you will find this is expected behaviour. It is because a circular routing like this is not possible in Isadora (where the output of an actor is wired through to the same actor input i.e. leads back to itself). I have hit this many, many times. You can think about placing a broadcaster and listener into the patch to overcome the limitation.

I try you'r patch and I have the same problems on Mojave... I made a video it's really strange because you couldn't change nothing on enveloppe generator... I tried to make a new patch with the same things and it's crazy too... sorry  I couldn't help you more.... 

if someone want's to see the screen capture of what it's happening...
