[TYPO3-mvc] Getting object uid after "add"

[Emmanuel Denoyelle]

Hi everyone,

I am wondering how to get an object uid just after adding it by the
repository.

For example :

$this->ficheRepository->add($newFiche);
$ficheId = $newFiche->getUid();


In this code, $ficheId stays uninitialize.

How can I get the uid of an objects that just have been added en the
database ?

Thanx
