Confused on pattern_correction

I am confused with the pattern_correction. Here is what the document says:

  • is_reset_only: indicates if the correction is only a reset of the flow
  • corrected_slots: slot key-value pairs that should be corrected
  • reset_flow_id: the ID of the flow to reset to, defaults to None
  • reset_step_id: the ID of the step to reset to, defaults to None

How could the system know that the correction is only a reset of the flow and set the value of ‘is_reset_only’? And I want to confirm that reset_flow_id means the parent flow the correction pattern is in ?

And Could you please give a concrete implementation of this situation?

User:I want to send some money to Joe

Bot:How much money do you want to send?

User:50$

Bot:Do you want to send 50$ to Joe? (Yes/No)

User:Oh wait!! I meant to say to John, not Joe!

Bot:Updated recipient to John

Bot:Do you want to send 50$ to John? (Yes/No)

User:…

How does my user-defined flow (like transfer_money) interact with the predefined flow pattern_correction. If the user only answer ‘No’ instead of giving the revise detail, how could my business logic lead him to correction logic?

Thanks for patience!

My flow is here. And I don’t know how to implement the ‘…’ part

flows:
  investment_plan_recommendation: 
    description: This flow recommend a investment plan to user according to user's portrait and needs. 
    steps:
      - collect: risk_tolerance_level
        description: "the level represents investors' acceptance and tolerance of investment risks, usually divided into five levels: conservative,cautious,prudent,proactive,aggressive"
      - collect: annual_income
        description: "the user's annual_income.If it's not on an annual basis, you should convert it."
      - collect: annual_outcome
        description: "the user's annual_outcome.If it's not on an annual basis, you should convert it."
      - id: confirm_info
        collect: confirm_slot_investment_plan_recommendation
        description: "the user confirm that the required information of investment plan recommendation is correct."
        next:
          - if: not slots.confirm_slot_investment_plan_recommendation
            #If the user needs to make modifications, there are two situations: 1. If the user also provides the modified content, the built-in patternic_correction will modify the slot value accordingly 2. The user did not provide any modified content
            then:
              ....
          - else:
            - action: action_customize_plan
            - action: utter_recommend_investment_plan
