Uncaught TypeError: Object #<an HTMLObjectElement> has no method 'ConnectToStream'

It produces this error even though everything is in place. May be it is because the external callback in Flash file is not getting registered with javascript.

This is probably because you are running test.html from your local file system, and not from a server. Default security restrictions prevent the ExternalInterface registration from working under that scenario. But you can go to http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html and go to the Global Security Settings and indicate that you trust the swf, and you'll be good to go. By the way, I figured this out by installing the debug Flash Player (plenty of instructions on the web for how to do this, even in Chrome) and saw the security error pop up that's suppressed by the release version of the player. By the way, use stream.twitter.com, not betastream.twitter.com.
