Thanks for the gist. Unfortunately, I've been unable to get this to work. I'm seeing that my app is loading the google maps .js file but no map is displayed. The last thing my pages loads is js from AuthenicationService.Authenticate that happens 4 seconds after everything else.
Any help would be greatly appreciated.
Thanks..
