[TYPO3-mvc] Problem calling a repository function

I can't get the objectManager in a render function of a view helper?

As trying

$projectRepository = $this->objectManager->get('Tx_UtekReferenzen_Domain_Repository_ProjectRepository');

Gives an exception that I try to call a member function on a
non-object.
