How to use Doctrine Module with Relations?

[c33s]

What are you trying to achieve?

i would like to add a product with a related category.

        $category = [
            'id' => 'CATEGORY_ID',
            'title' => 'Test Category',
        ];

        $product = [
            'id' => 'PRODUCT_ID',
            'title' => 'My Test Product',
            'category' => 'CATEGORY_ID',
        ];
        $I->haveInRepository('Entity\Category', $category);
        $I->haveInRepository('Entity\Product', $product);

What do you get instead?

setting category to a string [Doctrine\ORM\ORMInvalidArgumentException] Expected value of type "Entity\Category" for...
using categoryID as key leads to a category set to null (using propel before doctrine, i thought that this might work).

in general it sould be documented that invalid fields are dropped. i think this should throw an exception (should this go into different ticket?).
