flex+java 前台页面关闭后台报的异常，如何处理这种异常？

[解决办法]

Java code

private function exit():void{navigateToURL(new URLRequest('javascript:window.opener=null;window.close()'),'_self');}
[解决办法]
可以根据页面类型来选择关闭方法...楼上的适合application，
TitleWindow:
protected function titlewindow1_closeHandler(event:CloseEvent):void
{
// TODO Auto-generated method stub
PopUpManager.removePopUp(this);
}
Module
protected function btn_close_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub关闭
this.removeAllElements();
}
