I might pass in the item to resume as the sending object. The question then is which object is receiving the message, and from where is it sent?

Here's an example using the DP arrival (to stop and send a delayed message) and DP messagetrigger to resume.

DPstopMessageResume.fsm

In your example the decision point is sending the message to itself. So

conveyor.itemData[fromObject].resume();

resolves correctly. But if another object is sending the message then it does not. I get:

time: 4.958494 exception: FlexScript exception: MODEL:/Pos1>variables/Custom/onMessage


In another thread the reply used some kind of label on the object to point to the flow item. But I can't figure out how to do that. Here's that thread:

Why aren't there more pick list options for on message triggers? It seems like it would be incredibly useful.

Here's an example where the top conveyor's DP sends a message to the lower DP (centerObjects reference).

The lower DP ignores it if it doesn't have an item - which I set as a label on arrival and clear on message.remoteDPmessageResume.fsm
