title: as3 fl.transitions.Tween could not be found
body: <p>I need to do some work with some custom tweening and I understand how I'm suppose to do it. However CS5 is not able to resolve my import statements.</p>
  
  <p>I have </p>
  
  <pre><code>import fl.transitions.Tween;
  import fl.transitions.easing.*;
  </code></pre>
  
  <p>and both of these cause an error. The error is "definition fl.transitions.Tween or easing could not be found"</p>
  
  <p>The import statements are turning blue so flash is recognizing the path and I am able to import other fl components like fl.controls and fl.events. Why is my program unable to resolve these imports and how can I fix it? Please be explicit and detailed with any answers you give.</p>
  
  <p>Thanks a bunch.</p>
