Fixes catalogInventoryStockItemUpdate api call (V2) in Magento 1.8. Whats broken: The api method got refactored and now does not call $product->save() anymore. As a result the stock_id for new items is not set as the observer that takes care of that is hooked to the product_save_after event. Fix 1: Apply patch below. *OR* Fix 2: Update db schema…
