Error when picking virtualized items from rack using queryitems

Hi!

In my model I cant figure out how to pick virtualized items from a rack. I have a lot of items stored in my model so I want to use the virtualized items for the model to run faster. However, when I turn the setting of virtualizing items on, the model cant find the items.

I use queryitems() to get all items in one level for the ASRS to pick all these items.

Attached is a file with the same problem, virtualized_items.fsm

Software Version:

FlexSim 22.1.0

rack order picking virtualized items

Could you try to upload the sample model again? It seems the attachment didn't go through.

The query works correctly, but the label assignment when creating the sub flow tokens has two small errors:

- The dot-syntax method when accessing labels already returns the value (as opposed to object.labels["labelname"], which returns the label node). Due to this, using value in the expression causes an exception because it is not defined for the array values.

- The Storage.system.queryItems() method returns an array of "Storage.Slot.Item" class values.
