Hey all I’m working on a ROLL\_OVER event class and I’m stuck on an Error. Not sure what it is that I’m missing.

```auto
Error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::MouseEvent@2f6d661 to myCustomEvent.

```

My myCustomEvent

```auto
package {
    import flash.events.Event;
    public class myCustomEvent extends Event {
           // CONSTANTS
           public static const ROLL_OVER:String = 'rollOver';
           public static const CLICK:String = 'click';
           // VARS
        private var _body;
           // GETTERS/SETTERS
        public function get body() { return _body; }
           // CONSTRUCTOR
        public function myCustomEvent(type:String, body, bubbles:Boolean=true, cancelable:Boolean=false){
            _body = body;
            super(type, bubbles, cancelable);
            //
            trace("type:"+type+" bubbles:"+bubbles+" cancelable:"+cancelable);
            trace("body.name:"+body.name+", pram1:"+body.pram1+", pram2:"+body.pram2);
        }
           // PUBLIC METHODS
        override public function clone():Event {
            return new myCustomEvent( type, body, bubbles, cancelable );
        }
    }
}

```

```auto
package{
    //
    // ***********IMPORTS********** //
    import flash.events.Event;
    import flash.display.Sprite;
    import flash.display.Shape;
    //
    // ***********IMPORTS********** //
    //
  public class eventTest extends Sprite {
          private var thumContaner:Sprite;
        private var thumBack:Shape;
        private var thumArray:Array = new Array(0, 1, 2, 3, 4, 5, 6);
        private var thumObject:Object;
        private var thumID:Number = 0;
        private var thumX:Number = 0;
        private var thumGutter:Number = 10;
        private var thumName:String;
    public function eventTest():void {
        for each (var thumItems in thumArray){
            thumContaner = new Sprite();
            thumContaner.name = "thumContaner_"+thumID;
            thumName = thumContaner.name;
            trace("thumName: "+thumName);
            thumContaner.y = 300;
            thumContaner.x = thumX;
            thumContaner.alpha = 0.6;
            addChild(thumContaner);
            //
            thumBack = new Shape();
            thumBack.graphics.beginFill(0x666666);
            thumBack.name = "thumBack";
            thumBack.graphics.drawRect(0, 0, 56, 56);
            thumBack.graphics.endFill();
            thumBack.alpha = 0.6;
            thumContaner.addChild(thumBack);
            thumX = (thumX+thumGutter)+thumBack.width;
            // thum Object
            thumObject = {name:thumName, pram1:thumX, pram2:thumID};
            //
            thumContaner.addEventListener( myCustomEvent.ROLL_OVER, _EventROLL_OVER );
            dispatchEvent( new myCustomEvent( myCustomEvent.ROLL_OVER, thumObject ) );
            thumContaner.addEventListener( myCustomEvent.CLICK, _EventCLICK );
            dispatchEvent( new myCustomEvent( myCustomEvent.CLICK, thumObject ) );
            thumID++
        }
    }
        
    private function _EventROLL_OVER( e:myCustomEvent ):void {
        trace("body.name:"+e.body.name+", pram1:"+e.body.pram1+", pram2:"+e.body.pram2);
    }
    private function _EventCLICK( e:myCustomEvent ):void {
        trace("body.name:"+e.body.name+", pram1:"+e.body.pram1+", pram2:"+e.body.pram2);
    }
  }
}

```

This is what is trace output.

```auto
Output:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::MouseEvent@2f6d661 to myCustomEvent.

```

Thanks
