1120: Access of undefined property - moving functionality to external package

1120: Access of undefined property - moving functionality to external package

Hello dear Stackoverflowers! Here is my problem...
I'm trying to move some basic functionality for my object to external
package.
I've got MovieClip item in my library with name mcUnit: which is actually
a rectangle F8-ed in to Move Clip. I'm setting the AS Linkage to the
package I want it to use: clGameUnit;
Here is part of the clGameUnit code:
package
{
import flash.display.MovieClip;
import flash.geom.Point;
import flash.events.MouseEvent;
public class clGameUnit extends MovieClip
{
// Declaring all local object related variable
var clGU:MovieClip = new MovieClip();
var isOver:Boolean = false;
// Declaring all global object related variable
public var b_u_Selected:Boolean = false;
public var p_u_Coordinates:Point = new Point(clGU.x,clGU.y);
public var u_Image:int = 0;
//Declaring all object related methods
clGU.addEventListener (MouseEvent.CLICK, on_Object_LClick);
clGU.addEventListener (MouseEvent.MOUSE_OVER, onObjectMouseOver);
clGU.addEventListener (MouseEvent.MOUSE_OUT, onObjectMouseOut);
clGU.addEventListener (MouseEvent.RIGHT_CLICK, on_Object_RClick);
public function clGameUnit ()
{
}
....
}
}
And the error I get it:
1120: Access of undefined property clGU.
1120: Access of undefined property on_Object_LClick.
1120: Access of undefined property ... [other event listeners functions]
Already tried everything. Even making the constructor send the object to
the undefined property clGU:
public function clGameUnit (obj: MovieClip)
{
clGU = obj;
}
And on the time line I call this Constructor manually:
var mcGameObj: clGameUnit = new clGameUnit (mcGUnit);
mcGUnit is the Instance name for the mcUnit instance that I assign it in
properties. Here thing become even more complicated so I discarded this
variant.
Really need your help fellaz!
