Preload+classes

programming flash

Hello I have a problem with something pretty simple I can’t understand…
I have a fla file where I set the export classes frame to be different than 1 (the frame is 3 in this case) and on the fifth frame I have a stop(); action and a movie clip that’s instance of a class that’s linked to it from the library. And when the movie clip has no instance name everything is ok but when I give it one this error appears:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@2d14821 to Roller.

I have no clue how to fix it, please help.

Here’s an exemplary file:

Ok.
I has lincage MovieClip class


package {
     import flash.display.*; 
     import flash.text.*; 
     import flash.geom.*;
 
 
    public class Central_all_loading_prog extends MovieClip {
    public var my_txt:TextField;
 
 
        public function Central_all_loading_prog() {
              var txt:TextField = new TextField();
              txt.text = "I am loading for 2 frame";
              txt.autoSize = TextFieldAutoSize.LEFT;            
              txt.scaleX=txt.scaleY=3;
              addChild(txt);//
              my_txt = txt;
 
        }
    }
}

and Documen Class export in 2 frame? if I want new Central_all_loading_prog
in Document Class mast loading class Central_all_loading_prog


var Load_Central_all_loading_prog:Class = 
loaderInfo.applicationDomain.getDefinition("Central_all_loading_prog") as Class;

Document class all coding
