SKU cannot be added to cart, quantity available null

[ipapachristoudis]

We have successfully implemented a site based on 4.0.6 version of Broadleaf. Lately, we tried to upgrade to 4.0.14, but we face the problem that a SKU cannot be added to cart. In store we have some products and their additional skus produced on a product size option.

From a quick view of the matter, an InventoryUnavailableException is raised at service.workflow.CheckAvailabilityActivity.

Furthermore, in CheckAvailabilityActivity

• inventoryService.isAvailable(sku, requestedQuantity, inventoryContext) always returns false
• inventoryService.retrieveQuantityAvailable(sku, inventoryContext) always returns null

If we switch back to 4.0.6 everything works as expected.

All categories have InventoryType as CheckAvailability. Also setting one particular product and it's SKUs to have CheckAvailability option has no effect.

In front store, calling sku.getQuantityAvailable returns the correct value.

Any clue for the matter???

PS The same error affects all versions>4.0.6

Well, i found the solution to this.

There is a bug in InventoryServiceImpl, in retrieveQuantitiesAvailable(Collection skus, Map<String, Object> context) method.

The method checks some stuff, but doesn't set the available quantity when there is one.

The correct implementation of this method should be
`
public Map<Sku, Integer> retrieveQuantitiesAvailable(Collection skus, Map<String, Object> context) {
ExtensionResultHolder<Map<Sku, Integer>> holder = new ExtensionResultHolder<Map<Sku, Integer>>();
ExtensionResultStatusType res = extensionManager.getProxy().retrieveQuantitiesAvailable(skus, context, holder);
if (ExtensionResultStatusType.NOT_HANDLED.equals(res)) {

        Map<Sku, Integer> inventories = new HashMap<Sku, Integer>();
        for (Sku sku : skus) {
            if (checkBasicAvailablility(sku)) {
                if (InventoryType.CHECK_QUANTITY.equals(sku.getInventoryType())) {
                    if (sku.getQuantityAvailable() == null) {
                        inventories.put(sku, 0);
                    }else{
                        inventories.put(sku, sku.getQuantityAvailable());
                    }
                } else if (sku.getInventoryType() == null || InventoryType.ALWAYS_AVAILABLE.equals(sku.getInventoryType())) {

                    inventories.put(sku, null);
                } else {
                    inventories.put(sku, 0);
                }
            } else {
                inventories.put(sku, 0);
            }
        }

        return inventories;
    } else {
        return holder.getResult();
    }
}
