Issue with Push to List: Objects Created Inside Container vs Combiner Packing

[stayhometown]

Hi,

I am using two different packing methods and trying to push the contents into a list, but only one of them works and I don’t understand why.

In the first method, I directly create the boxes inside the container.
In the second method, I use a Combiner to perform the packing.

I checked the tree structure for the first method, and it does show that there are box subnodes under the tote. However, when I try to push them into the list, it doesn’t work. Only the second method succeeds.

Does anyone know why this is happening?

The tote that is created in the Process Flow enters Queue2 before the items inside it are created. You can see this when you step through the start of the simulation one event at a time with the "Step" button.

When creating nested flowitems in Process Flow I would recommend that you first create the container item inside some placeholder object (that is not connected to anything else) or the model itself. Only when everything has been created use a Move Object activity to place it in the target location.

Thank you for your reply. I didn’t notice that before, but now I understand how to handle it.
