Hello:

I have a issue with my webpage cart review. In our webpage all the products have aditional services like for example additional guarantee (if i bought the same wash machine 3 times i have to be able to choose aditional services for every one wash machines) .

My first idea is split every order line that have quantity greater than 1 into n orderlines with quantity 1.

So i made a Dynamicweb.Ecommerce.Notifications.Ecommerce.Cart.Line.Increased that split all order lines greather that 1 into n orderlines. It works well but this notification is executed 3 times before cart is being show to the user and it create more orderlines that the user says. I dont know why this happend, maybe is because the cart context, im not sure.

For example if i change a order line from 1 quantity to 3, my notification generates 6 order lines (1+2+2+2) . Here is a snapshot:

Here is the code of my increased notification:

 [Dynamicweb.Extensibility.Notifications.Subscribe(Dynamicweb.Ecommerce.Notifications.Ecommerce.Cart.Line.Increased)]
    public class EcomCartLineDecreasedObserver : Dynamicweb.Extensibility.Notifications.NotificationSubscriber
    {
        public override void OnNotify(string notification, Dynamicweb.Extensibility.Notifications.NotificationArgs args)
        {
            if (args == null || !(args is Dynamicweb.Ecommerce.Notifications.Ecommerce.Cart.Line.IncreasedArgs))
                return;

            
            Dynamicweb.Ecommerce.Notifications.Ecommerce.Cart.Line.IncreasedArgs item = (Dynamicweb.Ecommerce.Notifications.Ecommerce.Cart.Line.IncreasedArgs)args;

            
                OrderLineService orderLineService = new OrderLineService();
                int amountIncreased = (int)item.AmountIncreased;
                item.IncreasedLine.Quantity = 1;
                for (int i= 0; i < amountIncreased; i++)
                {
                    OrderLine ol= orderLineService.Create(item.Cart, item.IncreasedLine.Product, 1, new Dynamicweb.Ecommerce.Stocks.StockUnit(), item.IncreasedLine.UnitPrice);
                    ol.OrderLineFieldValues = item.IncreasedLine.OrderLineFieldValues;
                    ol.OrderLineFieldValues.First(v => v.OrderLineFieldSystemName.Equals("Retirada")).Value = "NO";
                    ol.OrderLineFieldValues.First(v => v.OrderLineFieldSystemName.Equals("Garantia")).Value = "NO";
                }

                Dynamicweb.Ecommerce.Common.Context.SetCart(item.Cart);  
            
        }
    }

Best Regards,

Jose.
