Data removed when using multiple repositories in same session

[p3mbo]

I have the following code that should create 2 simple products and a product relation. When adding a link via the link repository it seems to get rid of the stock from a product. This is not just limited to link repositories; adding a website via the website repository also has the same effect.

Code I'm using is similar to the below but correctly pushed through the constructor in my case:

        /** @var \Magento\Catalog\Api\ProductRepositoryInterface $productRepository */
        $productRepository = $this->_objectManager->create('\Magento\Catalog\Api\ProductRepositoryInterface');

        /** @var \Magento\Catalog\Api\Data\ProductLinkInterface $productLink */
        $productLink = $this->_objectManager->create('\Magento\Catalog\Api\Data\ProductLinkInterface');

        /** @var \Magento\Catalog\Api\ProductLinkRepositoryInterface $productLinkRepository */
        $productLinkRepository = $this->_objectManager->create('\Magento\Catalog\Api\ProductLinkRepositoryInterface');


        for($i = 1; $i <= 2; $i++ ) {
            /** @var \Magento\Catalog\Api\Data\ProductInterface $product */
            $product = $this->_objectManager->create('\Magento\Catalog\Api\Data\ProductInterface');
            $product->setSku('test_sku_' . $i);
            $product->setName('Test Product ' . $i);
            $product->setAttributeSetId(4);
            $product->setPrice(5);
            $product->setTypeId('simple');

            /** @var \Magento\CatalogInventory\Api\Data\StockItemInterface $stockItem */
            $stockItem = $this->_objectManager->create('\Magento\CatalogInventory\Api\Data\StockItemInterface');
            $stockItem->setIsInStock(true);
            $stockItem->setQty(50);


            /** @var \Magento\Catalog\Api\Data\ProductExtensionFactory $productExtensionFactory */
            $productExtensionFactory = $this->_objectManager->create('\Magento\Catalog\Api\Data\ProductExtensionFactory');
            $productExtension = $product->getExtensionAttributes();
            if ($productExtension === null) {
                $productExtension = $productExtensionFactory->create();
            }

            $productExtension->setStockItem($stockItem);
            $product->setExtensionAttributes($productExtension);

            $productRepository->save($product);
        }

        // If the code is exited here; the products are created with stock.


        // Related products one and two
        $productLink->setSku('test_sku_1');
        $productLink->setLinkedProductSku('test_sku_2');
        $productLink->setLinkType('related');
        $productLink->setLinkedProductType('simple');
        $productLink->setPosition(1);
        $productLinkRepository->save($productLink);

Expected Result:
2 Products created with 50 in stock and related to one-another via Related Products

Actual Result:
2 Products created with no stock and related to one-another via Related Products

@p3mbo magento.stackexchange.com is better place for such questions.

@piotrekkaminski I don't believe that this is a question - I believe it is a bug when using repositories and have provided code in order to re-produce it with an expected result and actual result.

e.g.
Expected Result:
2 Products created with 50 in stock and related to one-another via Related Products

Actual Result:
2 Products created with no stock and related to one-another via Related Products

Please can you re-open this issue; OR if this is expected behavior provide me with the documentation that suggests that this is behaving as intended..

I think it's awful that you wait 3 months without even acknowledging that I have posted an issue; and then come back trying to fob me off to Stack Exchange just in order to attempt to close the ticket to reduce the number of open issues.

@kandy - Thanks for re-opening this. I've just re-tested it with the newly released Magento 2.1 and it appears to have been resolved now; as have a lot of my issues that I have encountered around using repositories.
