Could not cancel the WebAuthenticationBroker.authenticateAsync() dialog after RP(Build 8400)

Question

Before Consumer Preview (Build 8250), we could cancel the dialog of WebAuthenticationBroker.authenticateAsync() just like cancel a Promise. For example,

authenticatePromise = Windows.Security.Authentication.Web.WebAuthenticationBroker.authenticateAsync(
Windows.Security.Authentication.Web.WebAuthenticationOptions.none,
new Windows.Foundation.Uri(oauthUrl), new Windows.Foundation.Uri(callbackUrl));

authenticatePromise.then(onCompleteCallback, onErrorCallback);

and call

authenticatePromise.cancel();

when we need to do this.

The dialog will be closed immediately and return error message 'Canceled'.

After Build 8400, call authenticatePromise.cancel(); will do nothing immediately.

But after user finished authentication or press back button, UI still receive error callback with 'Canceled' message instead of complete callback or "WebAuthenticationStatus.userCancel".

Is this new limitation?

And how to cancel the dialog of WebAuthenticationBroker.authenticateAsync() by code?

Hi Sars,

Can you post a real simple sample of this for me to investigate?  Can you simply modify the sample prehaps?

Hi Jeff,

I modified the sample "Snap View" to reproduce.

The sample for Build 8250: https://dl.dropbox.com/u/222042/SnapSampleWithWebAuth_8250.zip

And for Build 8400: https://dl.dropbox.com/u/222042/SnapSampleWithWebAuth_8400.zip

There is only two differences between these two sample: "//Microsoft.WinJS.0.6/" -> "//Microsoft.WinJS.1.0.RC/" and References in project setting.

Usage:

1. Open project and launch app

2. Click "Launch Web Auth" button

3. Drag app to snap view (or press "WinKey + . " on keyboard)

4(8250). In Build 8250, the dialog of WebAuthenticationBroker.authenticateAsync() will be closed

4(8400). In Build 8400, nothing happened

5(8400). Click "Back" button. Pop a message with "Canceled" message by error callback instead of complete callback

Thanks Sars!

Hi Sars,

I filed a bug for this.  This is incorrect behavior.  I do not have an ETA for a fix however.

Have this been fixed? I'm trying to use authenticateAsync() for facebook authentication following this sample at http://code.msdn.microsoft.com/windowsapps/Web-Authentication-d0485122

but I'm not sure if this bug is related. When the facebook login pop-up shows up, I can't close it by hitting on the Cancel button. It doesn't nothing.
