On the example below i have an html page with the javascript code needed to login to facebook.
On the i have the Google Chrome Frame
meta tag that makes the page run with google chrome frame. If you open this page with any browser the finish() callback runs normally.
If you open it with Google Chrome Frame it never fires.
So this means that every Facebook App that tries to login to gather user data cannot login.
This happens if the page is opened with google frame.
But even if i remove the
meta tag so that the page can open with IE8 the page opens again with google chrome frame because Facebook opens google chrome frame by default.
So because this is a Facebook app that runs inside an inside facebook.com it is forced to open with Google Chrome Frame!
SERIOUS BUG!
I have seen other people reporting it, someone has made a test facebook app also here:
http://apps.facebook.com/gcftest/
appID and channelUrl are dummy in the example below.
