Botframework-sdk: Microsoft Teams: postBack doesn't conform to documentation

[james-lawrence]

documentation
instead of just sending the message to the bot, the message is displayed and then sent to the bot. I also suspect that when this issue is fixed the message sent won't contain the id of the message containing the button (though it really should)

PostBack is not really supported in Teams at this time.

Please view the documentation at https://msdn.microsoft.com/en-us/microsoft-teams/bots#cards-and-buttons. We only support imBack and openUrl currently.

Closing this issue as it appears we've answered the open question. If you'd like to discuss further, please at-mention or open a new issue.

[james-lawrence]

@dandriscoll main question is will it be supported? openURL doesn't work for our usecase, as we don't want to send them to a url we just want an answer to the response, and imBack isn't useful because ideally we don't want the user seeing a encoded id, which is only useful for our system.

Yes we are currently working on PostBack support for Skype and for Teams, which will address exactly what you've mentioned above. Be on the lookout for an update in the near future.
