Question

I\'m using PromptDialog.Choice() to present different options to my users. The number of attempts is set to 0, so if they type in anything that is not a valid optio

Answer 1

Adding some more context to Ezequiel Jadib answer. I ran into a requirement similar to question mentioned in link below. Also, used one of the answer provided to the same question.

Calling back Luis from a forward dialog

Though the above question is marked as duplicate to current, I feel the Luis context is missing from this question.

If the Activity is created without Channel, From and Recipient information, you may end up with some exception while creating a reply. So, below code will help you create the right activity and set the correct message before handing it over to Luis

Luis Intent Method

    [LuisIntent("PerformSearch")]
    public async Task Search(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
    {
        var msg = await activity;
        msg.Value = result;
        await context.Forward(new SearchDialog(), ResumeAfterSearchPerformed, msg, CancellationToken.None);

    }

Resume After method for Forwarded Dialog

    private async Task ResumeAfterSearchPerformed(IDialogContext context, IAwaitable<object> result)
    {

        var msg = await result;            
        var userSearchString = msg.ToString();
        if (userSearchString.Equals("searchCompleted", StringComparison.InvariantCultureIgnoreCase))
        {                
            context.Wait(MessageReceived);
        }
        else
        {
            // At this point send the message back to LUIS MessageReceived 
            // method to re-identify the intent and trigger the method
            Activity myActivity = (Activity)context.Activity;
            myActivity.Text = userSearchString;
            await MessageReceived(context, Awaitable.FromItem(myActivity));
        }
    }

By doing above, you can easily create a reply from properly hydrated Activity

 Activity reply = ((Activity)message).CreateReply();
 reply.AttachmentLayout = AttachmentLayoutTypes.Carousel;

I think that calling MessageReceivedAsync will be the way to go here. The key is to pass an IAwaitable from the activity you are creating.

The code should be like:

await MessageReceivedAsync(context, Awaitable.FromItem(yourActivity));
