I see. In this case, you should reset the slots after the form is complete. To do this, I’d define a new custom action, say, action_reset_slots_xyz
and implement it to reset the slots of the form with SlotSet(..., None)
. Then, define a rule that executes this action after the form.
You could use a new separate slot (not used in the form) to keep track of past answers, if you need that.
