Runtime shared library

hello,

i’m using a custom framework (flex library project) inside of it is a custom class ListEvent that extends Event. when i’m loading this framework as runtime.swf (also link type as external because i want to load this library at runtime).Everything works great except the ListEvent class.

error

VerifyError: Error #1014: Class gr.synchronized.events::ListEvent could not be found.
at [verify]
at global$init()
at [abc-decode]

my Main.as code

package{

import flash.display.Sprite;
import gr.synchronized.components.List;
import gr.synchronized.components.Window;
import gr.synchronized.components.Label;
import gr.synchronized.util.StageUtilities;
import gr.synchronized.events.ListEvent;


public class Main extends Sprite{
    
    gr.synchronized.util.StageUtilities;
   gr.synchronized.events.ListEvent;
   gr.synchronized.components.List;
   gr.synchronized.components.Window;
   gr.synchronized.components.Label;
    
}

}

compile with mxml mxmlc Main.as -output runtime.swf

any ideas?
