I am making a processflow that creates trucks with its contents as labels. Afterwards the truck is filled with pallets. There is only three ports and transporters available so there is a list for each of these. When the trucks arrive, they wait until a port is available to create the objects in it. The trucks act as parent tokens and the pallets as child tokens. I am having trouble when it comes to transporting these pallets from the trucks to a sink. The trasnporters move correctly and the labels seem to work, but afeter the trasnporter gets to the first pallet it stops. The labels for each pallet are stored in an array inside a label of the parent token as well as the taskSequence labels. I need the port to be empty before another truck enters the port, that is why I am unloading the trucks during the process. I've been stuck on this for a while and don't know how to fix it.
