Effect that re-plans to a new intent, after an optional dialog event.

validate Example

When purchasing tickets to a show, we would like to not only fetch the user's email address, but also save it to their profile. We can do this when validating the incoming profile email using replan:

input (self) {
  type (profile.Self)
  min (Required)
  default-init {
    intent {
      goal: profile.GetSelf
    }
  }
  validate {
    if ("!(exists(self) && exists(self.emailAddresses))") {
      replan {
        intent {
          subplan {
            value { $expr(self.emailAddresses) }
            goal { @prompt-behavior(AlwaysElicitation) contact.EmailInfo }
          }
          goal { profile.UpdateSelf }
        }
      }
    }
  }
}

on-catch Example

We can use the replan effect to redirect the user when we catch a checked error from the action implementation. Here we redirect the user to the select payments screen upon detecting invalid payment information:

error (InvalidPayment) {
  on-catch {
    replan {
      dialog {
        template ("We couldn’t process the payment on your card. Please double check the details or try a different card")
      }
      intent {
        goal: ticketmaster.BuyTickets
        value: $expr(cart)
      }
    }
  }
}
