AS3: Type Coercion failed: cannot convert flash.display::MovieClip

Question

Updated:

Now I am recieving this error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip

From this class:

package com.George.MegaAmazingApp.Components
{
    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.MouseEvent;

    public class Wheel extends MovieClip
    {

        public function Wheel(area:MovieClip, diagram:MovieClip)
        {
            area.addEventListener(MouseEvent.CLICK, clickHandler);
        }
        private function clickHandler(event:MouseEvent):void
        {
            trace("wheel clicked");
            trace("this is diagram");
        }

    }

}

and this script:

import com.George.MegaAmazingApp.Components.*;

var wheel:Wheel = new Wheel(this.wheel,this.car);

Debug gives:

GeorgesMegaAmazingApp-app.xml doesn't exist in that directory but I don't know why it is looking there anyway, it is not where the fla is located.

Solution 1

Either this.wheel or this.car is not a MovieClip. Also could you turn on debugging in File > Publish Settings? You'll then get better error messages because, without more information, your error could be just about anywhere.

Edit:

Try renaming var wheel to something else because it seems that Flash is confused with your two wheel objects. For example, try:

var wheelObject:Wheel = new Wheel(this.wheel,this.car);

Solution 2

Is Wheel.as in the directory com/George/MegaAmazingApp/Components? (case-sensitive) Is that 'com' directory in a source path directory?
