Answer 1

What is $collab? You're getting Fatal Error trying to call get method on variable that was not properly initialized (non-object).

Answer 2

Your problem is in this lines:

return $this->getRepository()->findOneBy(array('username'=>$username));
$collab->get('collab.collaborateurservice')->findCollaborateurByUserName($this->getUser());

It should be:

return $this->getDoctrine()->getRepository('YourBundleNamespace:Collab')->findOneBy(array('username'=>$username));
$collab = $this->get('collab.collaborateurservice')->findCollaborateurByUserName($this->getUser()->getUsername());
