Streaming extensions: Difference in handling Adaptive Cards

[compulim]

Background

We send Adaptive Cards from a bot, but the result is different if the AC JSON is sent through Streaming Extensions vs. Web Socket.

The original JSON sent from the bot can be found at https://github.com/compulim/BotFramework-MockBot/blob/master/src/commands/Cards/Inputs.ts.

The screenshot shows JSON captured through network trace.

• Left one is Adaptive Cards sent through Streaming Extensions, same as raw JSON
• Right one is Adaptive Cards sent through Direct Line channel, altered

• Left one is through SE, with the Input.ChoiceSet in "compact" mode
• Right one is through Web Socket, with the Input.ChoiceSet in "expanded" mode

Looks like in SE, if style is not set, it default to compact. But in Web Socket, if it is unset, it default to expanded (set explicitly through Direct Line channel).

Reproduce

1. Go to https://compulim.github.io/webchat-loader
2. Click "Dev" on the version
3. Select "MockBot"
4. Click "Open Web Chat in new window"
5. Type "card inputs"
6. Observe the output
7. Open https://compulim.github.io/webchat-loader again
8. This time, select "MockBot with Streaming Extensions"
9. Click "Open Web Chat in new window"
10. Type "card inputs"

Expected result

They are the same. Either both in expanded state or compact state.

I am unsure if we should change the current behavior. But sending the JSON as raw as possible sounds like a better idea to me. But on the other hand, we should not change users' expectations.

Additional context

It is probably related to this, #87 (comment).

Documentation needs to be updated to highlight the difference in behaviour between directline and dl-ase
