TYPO3 Core

The sys_file_reference is not updated if detach a file from an objectstorage. If you try to delete the sys_file_reference with the repository, it tries to delete the sys_file with the uid from the sys_file_reference.

private function detachFilerefernce(\TYPO3\CMS\Extbase\Domain\Model\FileReference $file) {
$fileRepository = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\FileRepository');
$ref = $fileRepository->findByUid($file->getUid());
$ref->delete();
