Notice: Undefined property: JAdministrator::$JComp

Notice: Undefined property: JAdministrator::$JComponentTitle in D:\program files\wamp\www\j25\administrator\modules\mod_title\mod_title.php on line 13

在开发组件的时候，出现了这个错误。解决的方法是：

找到administrator\modules\mod_title\mod_title.php on line 13
将下面的代码：$title = JFactory::getApplication()-JComponentTitle;换成$title = JFactory::getApplication()-get('JComponentTitle');
