LUIS / Bot Framework multiple dialog, move intent handling to another dialog

Question

my goal is to implement both dialogs and LUIS into a Microsoft Bot Framework application using their C# SDK. I tried to follow this thread https://github.com/M

Answer 1

I had this same question, but I am using a newer version of Bot Framework, more specifically, V4.

Here is what I found:

• BeginDialogAsync's options parameter takes an array of objects that will then be accessible in your dialog.

// Get skill LUIS model from configuration.
localizedServices.LuisServices.TryGetValue("MySkill", out var luisService);

if (luisService != null)
{
    // Get the Luis result. 
    var result = innerDc.Context.TurnState.Get<MySkillLuis>(StateProperties.SkillLuisResult);
    var intent = result?.TopIntent().intent;

    // Behavior switched on intent. 
    switch (intent)
    {
        case MySkillLuis.Intent.MyIntent:
            {
                // result is passed on to my dialog through the Options parameter. 
                await innerDc.BeginDialogAsync(_myDialog.Id, result);
                break;
            }

        case MySkillLuis.Intent.None:
        default:
            {
                // intent was identified but not yet implemented
                await innerDc.Context.SendActivityAsync(_templateEngine.GenerateActivityForLocale("UnsupportedMessage"));
                break;
            }
    }
}

From our second dialog, we can access the object through the context and perform any casting, etc. as necessary. In my case, it was a waterfall dialog, so I used stepContext.options.

Try removing the Chain.From(() from the context.Forward call. Not sure why you are adding it, but it shouldn't be there at all.

Try with:

await context.Forward(new ProductsDialog(), ProductsDialogCompleted, context.Activity, CancellationToken.None);

And btw, if the message you forward hits the None intent the ProductsDialogCompleted method will be hit because you are doing context.Done, which basically ends the ProductsDialog.

Also, have in mind the StartAsync method is present in the LuisDialog<T> base class, so you need to add the override keyword.
