Weird behaviour stories

Hi,

I am using the restaurant example for forms and I am getting a weird behaviour. I separated greetings from the rest of the stories, and left everything the same. My issue is when I finish the form, the bot won’t recognise any other intent. So after finishing the form and saying thank you the state is

All done! I am going to run a restaurant search using the following parameters:

  • cuisine: mexican
  • num_people: 4
  • outdoor_seating: False
  • preferences: Nothing

And then if I say hi it understand the intent, but he is not able to track the conversation anymore, same happens if I try to book a table again, not recognition of Stories:

Hi there, it’s probaby because the stories don’t handle what happens after the form is over! This is a super simple example of a form that’s not meant to do much else other than show you how a form works. If you use the AugmentedMemoizationPolicy instead of the MemoizationPolicy, you should be able to follow multiple paths in succession. Another option would be to add action_restart to the end of each story – once you get to that spot the bot would clean the conversation history and start over.
