How can I communicate between processes using message events
I've got two processes ProcessEen and ProcessTwee. ProcessEen sends an intermediate message event which is pick up by the start of ProcessTwee. After that it will wait for ProcessTwee to complete.
When ProcessTwee ends it will sand and message event which should be picked up by the instance of ProcessEen. But it doesn't it keeps waiting for an event.
When using signals it works but when having multiple instances of ProcessEen thay all finish when one ProcessTwee instance is ready.
So my basic question is: How can I trigger the first process to continue using message events.
