[Calgacus map Brude]

Got the answer on stackoverflow, 
added thos ts to my ext setup
config.tx_extbase.persistence.classes.Tx_Extbase_Domain_Model_FrontendUser.mapping.recordType >

this is the code (it goes in my CouponController) that worked (plus the typoscript mentioned):

/** 
     * @var Tx_Extbase_Domain_Repository_FrontendUserRepository 
     */ 
    protected $userRepository; 

      /**  
       * Inject the user repository
       * @param Tx_Extbase_Domain_Repository_FrontendUserRepository $userRepository 
       * @return void */ 
      public function injectFrontendUserRepository(Tx_Extbase_Domain_Repository_FrontendUserRepository $userRepository) { 
          $this->userRepository = $userRepository;             
      }


public function showAction(Tx_Coupons_Domain_Model_Coupon $coupon) {

           $userRepository = $this->objectManager->get("Tx_Extbase_Domain_Repository_FrontendUserRepository");

            $newObject =  $userRepository->findByUid($coupon->getCreator());

            $this->view->assign('coupon', $coupon);
            $this->view->assign('creatorname', $newObject->getUsername() );

}
