Task Sequence error: Label does not exist

jingyong_p — Tue, 01 Sep 2020 23:43:51 GMT

[ FlexSim 20.2.1 ]

Task Sequence.fsmHere is what I am trying to do:

Queue 1 & Queue 2 generate different flow items.

Operator will pick 1 item from each queue to process them at Processor. (Trying to make it works like a combiner in process flow)

But I got error message : Label property item retrieved on token "id:1". Label does not exist. At activity "Load" in process flow "ProcessFlow"."

Please hlep. Thank you.

@jingyong.p, it looks like you are having trouble correctly referencing your pulled items. Not that when you pull an item from the list, you assign it to token.pulled. I changed this to token.pulled1 for the first pull from list and token.pulled2 for the second pull from list. These labels will create a reference to a token that you pushed to the list in your "Material" box:

Whenever you want to refer to the 3d item associated with the pulled token, you need to call token.pulled1.item or token.pulled2.item:

Lastly, you need to assign your task executer correctly in your "Create TS". You assigned the operator to token.operator in your "Acquire Operator" activity. You need to reference that in the "Assign Task Executer" field of your Create TS:

See the attached model for more details.

Thank you so much @benjamin.w2.

One more question: Is there better way to create a combiner in process flow?
