How to hook Luis into a Bot Framework FormDialog

Question

I have a Dialog class which is a FormDialog (say, FormDialog< SandwichOrder>; one which builds an order for a sandwich, as per the bot framework documentation website). The SandwichOrder includes a "Price" property.

I also have a Dialog class which derives from LuisDialog which gets the price (based on, say, the size and/or province).

How can I hook Luis functionality into a Form Dialog?

Answer 1

Currently it is not possible to call a Dialog in a form field step. But you can have your custom implementation of IRecognize for a Field in the form (in this case "Price") and in the IEnumerable<TermMatch> Matches(string input, object defaultValue = null) implementation call into your Luis model and return all the possible TermMatches based on the detected entities by Luis.

do you know if this functionality is being built in at all? It does seem a bit clunky to create our own custom fields simply for the purpose of jumping out to check a LuisIntent as well. – Krilov

It is definitely in the backlog. I suggest add this as an idea to the bot builder feedback site, so other people can vote for it. – Yseulta

Would love to submit it as an idea (think I may have already done so) But I since noticed that feedback.botframework.com is 'retired'. Any idea where it moved to? – Krilov

Answer 2

This post: Custom fields with FormBuilder in the Microsoft Bot Framework appears to suggest an answer, and a way to implement your own custom field which implements IRecognizer. I haven't gotten it to work yet though.
