我正在使用TYPO3 CMS 6.2.x LTS和Extension Builder编写TYPO3扩展。扩展应将 CSV 文件导入域模型，并在导入期间再填充两个模型。
CSV文件导入正常，但是以下控制器方法崩溃，我在解决问题时遇到问题。我相信问题的根源可能隐藏在我的插件调用第一个方法，但随后每个方法都直接转到下一个方法的事实中。Extbase 文档让我相信forward()不会返回到调用方法，我需要返回到原始方法以继续处理更多导入记录。
我的插件 URI 激活ImportMemberController->importAction() . ImportMemberController->importAction()传递一个$newPerson对象和一个$parameters数组，以PersonController->enrollAction()正常。 PersonController->enrollAction()传递$person、$role、$startTime和$stopTime对象，HasRoleController->commissionAction()正常。 HasRoleController->commissionAction()在最后一行persistAll()崩溃，并显示以下消息。
致命错误：在 null 中调用成员函数 persistAll（） typo3conf\ext\myextension\Classes\Controller\HasRoleController.php on 157路
包括 TCA 在内的配置通常与扩展生成器构建时相同。
下面是扩展的一些代码。对于长度，我深表歉意。

从对象管理器显式获取持久性管理器解决了这个问题。尽管持久性管理器注入已经存在于类的头部。
解决方案的线索来自Arek van Schaijk在findAll上对extbase中的非对象的评论，该解决方案的线索来自Arek van Schaijk的2015-05-26 14：18评论说："这里唯一可能发生的事情是injectProductRepository()没有很好地注入您的存储库（对象）。下一条评论说，"所以基本上所有的注射都被缓存了，并且没有检查是否有新的注射。显然，在某些情况下，Extbase 注入机制不会接合。
以下是有效的函数代码：
/**
* action commission
*
* @param MyNameSpaceMyextensionDomainModelPerson $person
* @param MyNameSpaceMyextensionDomainModelRole $role
* @param DateTime $startTime
* @param DateTime $stopTime
* @return void
*/
public function commissionAction(MyNameSpaceMyextensionDomainModelPerson $person,
MyNameSpaceMyextensionDomainModelRole $role,
$startTime, $stopTime) {
$objectManager = TYPO3CMSCoreUtilityGeneralUtility::makeInstance('TYPO3CMSExtbaseObjectObjectManager');
$newHasRole = $objectManager->get('MyNameSpace\Myextension\Domain\Model\HasRole');
$newHasRole->setStartTime($startTime);
$newHasRole->setStopTime($stopTime);
$newHasRole->addPerson($person);
$newHasRole->addRole($role);
$this->hasRoleRepository = $objectManager->get('MyNameSpace\Myextension\Domain\Repository\HasRoleRepository');
$this->hasRoleRepository->add($newHasRole);
$this->persistenceManager = $objectManager->get('TYPO3CMSExtbasePersistenceGenericPersistenceManager');
$this->persistenceManager->persistAll();
}
实际上不需要手动保留对象，因为如果在每个操作结束时与存储库相关联，extbase 会自动保留对对象的更改。
您注入了持久性管理器，但没有清除所有缓存....您必须清除所有内容以反映新的注射。在某些情况下，甚至可以清除 typo3temp 文件夹。
要在不需要使用安装工具的情况下为BE中的选定用户添加Flush system caches图标，只需编辑所需的帐户并将其添加到其TSConfig：
options.clearCache.system = 1
保存用户并通过按 F5 刷新整个 BE。
允许任何人清除系统缓存（尤其是在大型实例上）是一个相当糟糕的主意，因此仅对开发人员和聪明的管理员保留这种可能性。
