How to debug swc files in Flash CS5

Question

Hi, to coin a familiar phrase "I'm new to Flash developement". My question is very simple. How do I debug .swc files (that I've created in Flash Builder 4) in Flash Professional CS5. I've incorporated the .swc file in the Publish Settings->Flash tab. But when I attempt to consume the objects in the .swc file I get an error saying it "Cannot display source code at this location."
Can someone tell me the best pratice for debugging .swc files. Do I debug them in Flash Builder or Adbobe Professional Flash CS5?

I think I found the solution to my problem..... but dont know how to implement it correctly.
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/StageScal eMode.html#SHOW_ALL
I believe I need to use the SHOW_ALL constant, but there isn't an example of how to do it
Heres my code, it compiles without errors, but when I publish it as .exe I get the 'Error 1037: Package cannot be nested':
package
          import flash.display.StageScaleMode
          import flash.media.Camera;
          import flash.media.Video;
          public class ScaleMode
                    public static const SHOW_ALL:String = StageScaleMode.SHOW_ALL;
                    var camera:Camera = Camera.getCamera();
                    if (camera != null) {
                              videoTwo.attachCamera(camera);
                    } else {
                              trace("You need a camera.");
          stop();
Any ideas??
