You have answers where I have described how to hold items in the rack and how to release an defined item. LIFO releases the last item entered the rack.

Dot syntax for new versions

Object myRack = Model.find(“Rack1”);
releaseitem(myRack.last,1);

Older versions

treenode myRack = node(“/Rack1”,model());
releaseitem(last(myRack),1);

Please consider, a released item is ready for transport. If an item is entering the rack while another item is waiting for transport, you won’t establish a straight LIFO. If something like this occurs, you must bring the taskexecuter really near to the LIFO item before you release the item.

This approach hasn't got any relation to the origninal question. You are pulling items by their rank, not LIFO. Please ask a new question! Regards Jörg
