Pull from list (Use Max Wait Timer) On Wait Timer Fired token flow.

As shown in below images, tokens enter into activity Is there a Parking Spot? (pull from list activity) and then tokens are going into backorder.

As tokens entered into backorder which I understood as the tokens failed to pull items from list. So, I am expecting it should trigger Use Max Wait Timer and OnWaitTimerFired and token should go to connector 2 i.e. No connector. But still the tokens are passing through connector 1 i.e. Yes connector.

I am trying to understand how this token flow is happening. Please any feedback on this.

I am attaching the model for reference.

Since you have the Park Points control point connections set to use a list, the AGV Network pushes all the Park Point connections on the list at time 0. Here's the timeline of what's happening.

  1. Tokens get to the "Is there a Parking Spot" activity.
  2. There are no entries so the tokens create a backorder and create an event at the end of time 0 to check the Max Wait Timer.
  3. The AGV network pushes all the Park Point connections to the list.
  4. All the token backorders are fulfilled before the Max Wait Timer fires and the tokens move out connector 1.

This is all working as expected.

If you really want the tokens to go out connector 2 before the Park Points connections are added to the list you should set the Max Wait Timer to be No Wait (choose it from the drop down) instead of 0.
