我viewhelper为扩展创建了一个自定义小部件，该小部件在空的typo3 8.7 安装中运行良好。但是当我用相同的代码在需要的项目上使用它时，它会导致错误：

#1289422564: initiateSubRequest() can not be called if there is no valid controller extending TYPO3\CMS\Fluid\Core\Widget\AbstractWidgetController Got "NULL" in class ...

以前有人遇到过这样的错误吗，或者有人知道导致这种错误的原因吗？

我得到了同样的错误。您需要注入控制器，就像在流体分页小部件中完成的那样。这部分在书中没有。

<?php
/**
 * This is the SortViewHelper
 */

namespace MyVendorName\MyExhibitors\ViewHelpers\Widget;


class SortViewHelper extends \TYPO3\CMS\Fluid\Core\Widget\AbstractWidgetViewHelper
{

    protected $controller;

    /**
     * @param Controller/SortController $controller
     */
    public function injectSortController(Controller\SortController $controller)
    {
        $this->controller = $controller;
    }

    /**
     * @param \TYPO3\CMS\Extbase\Persistence\QueryResultInterface $objects
     * @param string $as
     * @param string $property
     * @return string
     */
    public function render(\TYPO3\CMS\Extbase\Persistence\QueryResultInterface $objects, $as, $property)
    {
       return $this->initiateSubRequest();
    }
}
