Limit the items on a gravity flow rack

I want to limit the items in my gravity flow rack. I only want to items per slot in my rack. I tried to customize the code of "Slot Assignment Strategy" but it didn't work:

Can someone help me?

Did you add the "items" label to the slot. Because that's not a default expression. Other than that the code looks like you are trying to count the amount of items of a specific type in the slot. But due to the matching labels condition items with a different type can't be in the slot in the first place, no?

You can check how many items are assigned to a slot through the slotItems property of the slot class. So to limit the total quantity per slot you would just add "slot.slotItems.length < 2" to the condition.

If I add the "slot.slotItems.length <2" it still doesn't work.. here is my testfile.

The slot is assigned in Process Flow, so that's where you have to add the condition.
