Array index out of bounds: Assign Labels

example model.fsm

Hi,

4 totes arrive at buffer2 every 10 seconds, each tote will be sent to the input queue of the processor.

I assign a label called destination, value is the input queue of processor.

But it comes out exception error, what's wrong with the activity assign label?

Any advices is much appreciated.

The processors WireBond12, 13 and 14 are not connected to their queue. So "inObjects" is empty and trying to read the first inObjects causes the error.

After connecting processors and queues, the model still not working well.

In Processor process flow, I found that token enters <Push to List> has assigned label <destination>, however when I check the entries, the <has destination> label is still equals to zero. Therefore, agv can't pull anything from the list.

Any mistakes in my push to list/pull to list event?

The "destination" label is written to the token, but the item is pushed to the list. Since the item still doesn't have the label, the "hasDestination" field returns 0.
