In a form, the slot that I want to request is a list. This slot is never requested What I’m seeing is that when the form action is called, the slot is set to an empty list before we get to actions I can control in stories or rules. My guess is it’s not being requested is because it’s not null or None. Has anybody else seen this? Is there a work around?

Yes, the problem is that an empty list is still a list. Check this thread for a solution with two slots.
