Microsoft BotFramework FormFlow PromptInStart跳至功能后的恢复

Question

I'm trying to start a FormFlow from a LuisDialog:

[LuisIntent("bookConfRoom")]
public async Task BookConferenceRoom(IDialogContext context, LuisResult result)
{
     IDialog<RoomBooking> roomBookingDialog = MakeRootDialog();
     context.Call(roomBookingDialog, RoomBookingComplete);
}

MakeRootDialog() builds the FormFlow form:

internal static IDialog<RoomBooking> MakeRootDialog()
{
     return Chain.From(() => 
        FormDialog.FromForm(RoomBooking.BuildForm, options: FormOptions.PromptInStart));
}

And RoomBooking looks like this:

[Serializable]
public class RoomBooking
{
    public LocationOptions MeetingLocation;
    public DateTime MeetingTime;
    public double NumberOfHours;
    public int NumberOfAttendees;
    public List<AmenitiesOptions> Amenities;

    public static IForm<RoomBooking> BuildForm()
    {
        return new FormBuilder<RoomBooking>().Build();
    }
}

When that intent is hit the resume after function RoomBookingComplete runs immediately without the FormFlow appearing. However if I remove FormOptions.PromptInStart then the FormFlow does run, but you have to send another message to the bot before it starts, which is what I thought PromptInStart would fix?

I think I'm getting confused with the order of the Dialog stack and/or which dialog context I'm in. Any help will be appreciated.

Answer 1

You should remove the Chain.From

internal static IDialog<RoomBooking> MakeRootDialog()
{
     return FormDialog.FromForm(RoomBooking.BuildForm, options: FormOptions.PromptInStart));
}
