[TYPO3-mvc] repository->add => persistenceManager->persistAll => repository->findBy

[Daniel Dimitrov]

Hey guys,
I'm making an Ajax request that saves a product and immediately after that 
returns the saved product together with all other saved products for the 
user. Sadly I have a small problem with the returned object one of the 
properties is of type Tx_BwShop_Domain_Model_Products, but the ajax request 
returns it as INT.

In my controller I have the following code:
	public function addToCartAction() {
		$sessionId = $this->cartModel->getUserSessionId();
		$this->cartModel->setSessionId($sessionId);
		$this->cartModel->setProduct($this->getParametersSafely('product_id'));

		$this->cartRepository->add($this->cartModel);

		$persistenceManager = Tx_Extbase_Dispatcher::getPersistenceManager();
		$persistenceManager->persistAll();

		$products = $this->cartRepository->findBySessionId($sessionId);

		var_dump($products);

		$this->view->assign('products',$products);
	}

After using the repository add method I immediately call the persistence 
manager to store the object, because I need it in my next database request.
The product is stored in the database and I retrieve it, the problem is that 
the product is not mapped with the Tx_BwShop_Domain_Model_Products.

My Cart model is defining the product as follow:
	/**
	 * @var Tx_BwShop_Domain_Model_Products
	 */
	protected $product;

but the var_dump shows:
array(1) {
  [0]=>
  object(Tx_BwShop_Domain_Model_Cart)#66 (7) {
    ["sessionId:protected"]=>
    string(32) "8e5ae12d9b922b5e16a5e76bb75486ca"
    ["product:protected"]=>
    int(903)
    ["_cleanProperties:private"]=>
    array(3) {
      ["sessionId"]=>
      string(32) "8e5ae12d9b922b5e16a5e76bb75486ca"
      ["product"]=>
      int(903)
      ["uid"]=>
      int(174)
    }
    ["uid:protected"]=>
    int(174)
    ["_localizedUid:protected"]=>
    NULL
    ["_languageUid:protected"]=>
    NULL
    ["_isClone:private"]=>
    bool(false)
  }
}

as you can see product is int and not a Tx_BwShop_Domain_Model_Products.

Any ideas? Must I somehow start the mapping for the product manually?

Kind regards,
Daniel
