Код:
this.myFooter.muter.muter.addEventListener(MouseEvent.CLICK, muteSoundNow);
this.myFooter.muter.muter.dispatchEvent(new MouseEvent(MouseEvent.CLICK, true, false));
в функции muteSoundNow ставлю trace(event); на выходе то что ниже:
[MouseEvent type="click" bubbles=true cancelable=false eventPhase=2 localX=NaN localY=NaN stageX=NaN stageY=NaN relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0]
TypeError: Error #1009: Cannot access a property or method of a null object reference.
