title: create a FlashBuilder4 mxml class instance using ActionScript?
body: <p>I have a number of GUI dialogs defined using MXML.  Assuming these mxml objects have been compiled into my application, is there any way to instantiate these objects using ActionScript, sort of like this?</p>
  
  <pre>
      myFoo:  Mxml2ActionScriptClass("FOO.mxml") = new AutomagicalMXMLFactory( "FOO.mxml");
      myFoo.addEventListener(etc etc)
      this.AddChild(myFoo);
  </pre>
