Can we send a message to a ProcessFlow activity?

I'll try to keep this brief. I would like to send a message to a Wait for Event activity, which is listening to the `OnMessage` trigger of `activity` (see below).

I am getting an error - invalid triggering event. I'm assuming this is because ProcessFlow activities can't receive messages. Is this the case? I would like to avoid sending a message to the ProcessFlow object itself, but I'll do this if I absolutely need to. If I can't send a message to the activity, what other options do I have? Is there a list of what can or cannot receive messages?

Thank you.

A message creates an event and parses data. You achieve the same by creating a token and add label data to it.

Consider instead using a global list partitioned by UnitOpID to handle the coordination.

Instead of the wait for event activity, use a push to list activity and then have the 'would-be' message event pull value(s) off the list - again referencing the UnitOpID partition.

The process flow activities probably don't inherit from the FlexSimEventHandler class.

Thank you. I'm going to modify this a little but this idea should work for my purpose.
