title: Apache Flex 4.8.0 not working in Flash Builder 4.7
body: <p>Yesterday, I started using Apache Flex 4.8.0 in my Flash Builder 4.6. Everything works fine, thanks to a tutorial on <a href="http://lucamezzalira.com/2012/07/24/how-to-install-flex-4-8-0-sdk-in-flash-builder/" rel="nofollow">http://lucamezzalira.com/2012/07/24/how-to-install-flex-4-8-0-sdk-in-flash-builder/</a>
  Now, I downloaded the beta of Flash Builder 4.7. The release notes state that Apache Flex 4.8.0 is supported. However, when I try to add it to my SDK list, it says "directory does not contain a flex sdk". I have no other options whatsoever. I just did the same as in the tutorial. what's wrong=</p>
