Error #1009 in cs5.s with updateAllControllers()

I just tried your senario. I can't reproduce it in my simple project... Can you share your code scrapt to us so that we can identify where the problem is.

One more idea. Please try to operate the TLFTextField after your MovieClip has been added to the stage. I always try to operate the TLFTextField using the following codes:

package  {

          import flash.display.MovieClip;

          import flash.events.Event;

          import fl.text.TLFTextField;

          import flashx.textLayout.elements.TextFlow;

          import flashx.textLayout.events.CompositionCompleteEvent;

          public class test extends MovieClip {

                    private var activeFlow:TextFlow = null;

                    public function test() {

                              // constructor code

                              super();

                              trace("hello world");

                              addEventListener(Event.ADDED_TO_STAGE, importxml);

                    }

                    private function importxml(evt:Event):void

                    {

                              trace("importxml");

                              activeFlow = testText.textFlow;

                              activeFlow.flowComposer.updateAllControllers();

                    }

          }

}
