NopCommerce EF problems

I am using nopcommerce for my web shop and I am using Tasks that are getting information from an external system when an order has been shipped. When it is shipped I want to capture the payment and then set it as shipped. However, I keep getting EF errors. Any way to get around this for now? I need to have it up and running

An entity object cannot be referenced by multiple instances of IEntityChangeTracker.

See my code below:

                int orderId = PBSManager.GetOrderIdByCustomOrderNumber(customOrderNumber);
            NopObjectContext db = ObjectContextHelper.CurrentObjectContext;
            Order order = db.Orders.SingleOrDefault(c => c.OrderId == orderId);
            //Incorrect or开发者_高级运维der id    
            if (order == null)
            {
                //Skip this one if we cannot find the id
                continue;
            }
            if (OrderManager.CanCapture(order))
            {
                string error = string.Empty;
                OrderManager.Capture(order, ref error);
                if (!string.IsNullOrEmpty(error))
                {
                    PBSManager.HandleCaptureError(order, error);
                    return;
                }
            }
            if (OrderManager.CanShip(order))
            {
                OrderManager.Ship(order.OrderId, true);
            }

I am just guessing that probably you are creating another context in the OrderManager class. You should use the same context.

Can this link be of any help

Multiple instances of context

Doesn't nopCommerce store the current context in the HttpContext, have you tried looking for it in there?
