Doctrine ObjectSelect上引用实体的数据类型错误

I have a form which uses Doctrine's ObjectSelect to make a dropdown

        'name' => 'category',
        'type' => 'DoctrineModule\Form\Element\ObjectSelect',
        'options' => array(
            'label' => 'Category',
            'object_manager' => $em,
            'target_class' => 'Blog\Entity\Category',
            'property' => 'name'
        'attributes' => array(
            'required' => true

the issue I have, is that this should reference the id of another entity, howeve it keeps throwing "Expected value of type "Blog\Entity\Category" for association field "Blog\Entity\Post#$category", got "string" instead."

here´s the var_dump from the form, the important part

  protected 'factory' => null
  protected 'data' => 
    array (size=5)
      'id' => string '' (length=0)
      'title' => string 'asdasd' (length=6)
      'content' => string '<p>asdasd</p>' (length=13)
      'category' => string '3' (length=1)
      'submit' => string 'Add' (length=3)

and my addAction

public function addAction()
    $form = new PostForm($this->getEntityManager());
    $form->setHydrator(new DoctrineEntity($this->getEntityManager(),'Blog\Entity\Post'));


    $request = $this->getRequest();
    if ($request->isPost()) {
        $post = new Post();


        $em = $this->getEntityManager();
        $this->flashMessenger()->addSuccessMessage('Post Saved');
        return $this->redirect()->toRoute('post');
     return new ViewModel(array(
        'post' => $post,
        'form' => $form

How would I solve this, I don't get how it doesn't complain about the ids but for this it does.

UPDATE ** category entity ORM anotations

 * @ORM\ManyToOne(targetEntity="Category")
 * @ORM\JoinColumn(name="category_id", referencedColumnName="id")
private $category;

    What are your hydrator settings on this fieldset?

    For example;

    $this->setHydrator(new DoctrineHydrator($em, 'Blog\Entity\Category'))
                     new Category()
