[TYPO3-mvc] Set Validators inside an Action

[Oliver Beck]

Hi all

I know it's possible to add custom Arguments Errors inside an action (with \TYPO3\CMS\Extbase\Mvc\Controller\ArgumentError).  But with this solution I have to create a new validation error (with its own error code and message). But I want to use existing validators like the NotEmpty-Validator.

Thanks for any hints!

Kind Regards, Oliver
