I updated my Facebook tutorial with a different login method. I don't use the javascript method so I'm not sure if the plugin works. :(
Updated Tutorial with new capx
These work out of the box if you follow the updated directions, this can be seen at My shopping example
Notice on the website your name shows up. If you look in the capx you will see I never login using the facebook plugin and the user access token is available in the address bar for graph calls..... I know this doesn't fix the bug, just wanted to point you to a different way to log in.
