Symfony -> overwriting existing entity on update - php

Question

Im creating a simple user class
- User -> entity
- Address -> entity
When a user got created i create a address record in my db.
Now when a user gets edited and changed his addres :
If the address exist he need to take that existing address
if the address not exist Symfony needs to create a new one and use the new address.
Atm I can create users and their address, but when I edit a users address:
The current existing adress get overwrited instead of creating a new one.
Maybe i missed some logic or am i doing it wrong.
here's my code :
public function editAction(Request $request,Users $user)
{
$form = $this->createForm(UserForm::class, $user);
if ($request->getMethod() == 'POST') {
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$form = $form->getData();
$this->tryEditAction($user, $form);
return $this->redirectToRoute('admin_userslist');
}
}
$label = "Gebruiker aanpassen";
return $this->render('#ProjectUser/backend/edit.html.twig', array(
'form' => $form->createView(),
'user' => $user,
'label' => $label,
));
}
And here is the TryEditAction :
public function tryEditAction($user, $form)
{
$formAddress = $form->getAddress();
$formAddressStreet = $formAddress->getStreet();
$formAddressStreetNr = $formAddress->getStreetNr();
$formAddressStreetBus = $formAddress->getStreetBus();
$entityManager = $this->getDoctrine()->getManager();
//***
// Getting the entitymanager to get all addresses stored in our db
// Check if this address exist, so we change or edit the address accordingly to the user
//**
$address = $entityManager->getRepository('ProjectLocationBundle:Address')
->findOneBy(
array(
'street' => $formAddressStreet,
'street_nr' => $formAddressStreetNr,
'street_bus' => $formAddressStreetBus
)
);
if($address):
$foundAddress = $address;
$user->setAddress($foundAddress);
$foundAddress->setUser($user);
$entityManager->persist($foundAddress);
else:
$newAddress = new Address();
$newAddress = $formAddress;
$entityManager->persist($newAddress);
$entityManager->flush($newAddress);
$user->setAddress($newAddress);
endif;
// dump($user); die;
$userName = $user->getUsername();
$slug = $this->slugify($userName);
$user->setSlug($slug);
$entityManager->persist($user);
$entityManager->flush();
return $user;
}
