Linking different BPM instances


Dear all,
I tried to synchronize two process together deployed separately.
Process A blocks on a catch event. Process B throw the event and when A catch the event it must be unlocked.
I tried but it does not work, I did not find any solution on web. Is it possible to make it working with the strictly condition that the two processes are separated (either in the modeler and in the cockpit when deployed)?


Can you upload your processes so that i have a better idea what exactly you’ve tried and what you’re trying to accomplish.
