I've been following the tutorials here http://www.adobe.com/devnet/facebook/articles/flex_fbgraph_pt4.html for making Facebook apps using Flex. The desktop app worked just fine (I even added some custom stuff to test out features and learn the API). However when I switch to a web app (swf), following that tutorial, the Facebook.init() function doesn't even do anything. It never calls the loginHandler function, therefore never logging in? What's up with this?
