That is a missing feature still unfortunately, see [1]

For now you can create a validator or check the existence in the 
controller like:

if ($this->userRepository->findOneByUsername($username) !== NULL) {
	$this->flashMessageContainer->add('Username already used');
	$this->redirect(...);
}


makes me think of another nice Fluid widget that checks the availability 
of a unique property via ajax..

Best,
Bastian
