Actionscript 3 如何在flex 4.6 mobile中打开方法后立即关闭弹出窗口

当调用popup.open方法时，如果未触发打开事件，我将立即使用popup.close方法关闭弹出窗口。问题是弹出式容器中的内容已创建，但尚未完全从阶段中删除，因此我无法单击按钮。请运行下面的代码，并告诉我如何从第二次点击按钮的解决方案

添加PopUpManager.removePopUp（SPRCRL）后问题得到修复

<fx:Script>
    <![CDATA[
        import flash.utils.setInterval;

        private var sprCtrl:SpinnerControlWithText;
        private var timer:Timer = new Timer(1);

        protected function button1_clickHandler(event:MouseEvent):void
        {
            sprCtrl = new SpinnerControlWithText();
            sprCtrl.open(this,true);
            sprCtrl.x =0;
            sprCtrl.y = 0;
            sprCtrl.width = this.width;
            sprCtrl.height = this.height;
            sprCtrl.close();//Here i have to close this in backend response
        }
