Symfony 2: cannot add a User-Entity to a Item-Entity as it's owner

Question

I'm trying to add a User to the Item as it's owner

• manually in the Controller by $item->setOwner($this->getUser());
• in a ManyToOne-relation.

Everything defined in the FormType gets saved as it should but the owner_id is NULL. I don't get any error-message.

Any ideas? Code below.

Thanks in advance!

# src/myBundle/Controller/myController.php
class myController extends Controller {
    public function myAction(Request $request) {
        $item = new Item();
        $item->setOwner($this->getUser());

        // print_r($this->getUser());  <- prints a valid user

        $form = $this->createForm(new ItemFormType(), $item);
        if ($request->isMethod('POST')) {
            $form->handleRequest($request);

            if ($form->isValid()) {
                $em = $this->get('doctrine.orm.default_entity_manager');
                $em->persist($item); // saves everything but the owner
                $em->flush();
            }
        }

        return $this->render('myBundle:path/to:template.html.twig', array(
            'form' => $form
        )
    }
}

Problem solved. Unfortunately I didn't change the column-name of $deletedBy after copy & pasting $owner. Result: $deletedBy overwrote $owner with an empty value.

# src/myBundle/Entity/Item.php
class Item {
     // ...
     /**
      * @ORM\ManyToOne(targetEntity="myBundle\Entity\User")
      * @ORM\JoinColumn(name="owner_id", referencedColumnName="id")
      */
    protected $owner;

    // many more

    /**
      * @ORM\ManyToOne(targetEntity="myBundle\Entity\User")
      * @ORM\JoinColumn(name="owner_id", referencedColumnName="id") <- "owner_id"
      */
    protected $deletedBy;

    // ...
    // Getter & Setter
    // ...     
}
