[TYPO3-mvc] catch the uid within the create Action of a controller

[Mario Beiser]

Hi there,

just trying to figure out, if it is possible to catch the Uid of a 
record created in the following way:

public function createAction(Tx_Test_Domain_Model_FrontendUser $user) {
...
$this->userRepository->add($user);
print_r($user->getUid());
...
}

So the goal is to have the UID of the actual created record within the 
CREATE action. When I print out the user object, the uid isn't listed in 
the public vars. Unfortunatelly I have to call the getUid-method after 
adding, because before I didn't do this, there is no uid :-)
So am I correct when saying that there is no supporting of getUid-method 
in the create-Action?

Thanks a lot in advance.
Mario
