我正在使用 AJAX 创建一个组件，单击提交按钮后jos-Error: Unable to load renderer class出现错误。我的猜测是控制器找不到视图：
public function savex()
{
JRequest::setVar('view', 'komentarai');
parent::display();
}
但我不确定这是否正确。
还有一些我得到的其他错误（更具体的控制器）

SienaController -> savex() @ C:\xampp\htdocs\libraries\joomla\application\component\controller.php:761
