[TYPO3-mvc] How to add a unique/primary key property to a manually created domain model?

[Jan Kornblum]

I've just seen that some parts of the post have been corrupted when 
watching it on forum.typo3.org instead of using a classical newsreader 
(I've just created a bugreport). Another try:

Hi Henjo,

thanks for spending time to my tries

> Why not save the uid's and the amount of products to a session and write a
> service or utility class to do CRUD on the session cookie?

This is what i would try next as another approach.

> Or - and that's an aproach I am taking in a current project - create an

And maybe this as a third, certainly best approach

Maybe it it not the best example for me when still young with extbase

> When you have a Basket Object with a relation to an ObjectStorage

First of all i would like to get it work with this approach. But i 
can't figure out my mistake.

Parts from my BasketController:
---

/**
 * The object repository
 * @var \XX\Ext\Service\UserSession
 * @inject
 */
protected $userSession = NULL;

/**
 * action addProduct
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function addProductAction(\XX\Ext\Domain\Model\Product $product) 
{
    $basket = $this->userSession->getBasket();
    $basket->addProduct($product);
    $this->userSession->saveBasket($basket);
    $this->redirect('list', 'Product');
}

/**
 * action removeProduct
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function removeProductAction(\XX\Ext\Domain\Model\Product 
$product){
    $basket = $this->userSession->getBasket();
    $basket->removeProduct($product);
    $this->userSession->saveBasket($basket);
    $this->forward('list', 'Product');
}

And parts from my BasketModel:
--

/**
 * products
 *
 * @var 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product>
 */
protected $products;

/**
 * __construct
 *
 * @return Basket
 */
public function __construct() {
    $this->initStorageObjects();
}

/**
 * Initializes all ObjectStorage properties.
 *
 * @return void
 */
protected function initStorageObjects() {
    $this->products = new 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}

/**
 * Adds a Product
 *
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function addProduct(\XX\Ext\Domain\Model\Product $product) {
    $this->products->attach($product);
}

/**
 * Removes a Product
 *
 * @param \XX\Ext\Domain\Model\Product $product
 * @return void
 */
public function removeProduct(\XX\Ext\Domain\Model\Product $product) {
    $this->products->detach($product);
}

/**
 * Returns the Products
 *
 * @return 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product> 
$products
 */
public function getProducts() {
    return clone $this->products;
}

/**
 * Sets the Products
 *
 * @param 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\XX\Ext\Domain\Model\Product> 
$products
 * @return void
 */
public function 
setProducts(\TYPO3\CMS\Extbase\Persistence\ObjectStorage $products) {
    $this->products = $products;
}

And the BasketView contains the following link:
--

[...] link.action action="removeProduct" arguments="{product : 
product}"  controller="Basket" pluginName="Pi1" [...]


But calling this link doesn't remove the product. Argument-mapping 
seems to work correctly, as when i vardump the $product param inside 
BasketControllers removeProduct()-Action, the ProductObject seems to be 
as it should. But it doesn't get removed

Can you see any mistake? Currently there seem to be to many trees and i 
can't can't see the forest

Kind regards, Jan
