[TYPO3-mvc] Using repositories in validators

[g4-lisz at tonarchiv.ch]

Hi Matthew

I don't know if this helps, never tested it myself in a validator:

Maybe you should use the ObjectManager, like:

            $objectManager =
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Object\ObjectManager');
            $bemerkung =   
$this->objectManager->get('NS\Extname\Domain\Repository\ReservationRepository');

And: I dont't use double backslash in my methods for the object path...

Cheers,
Till
