ExportManager.ExportOrdersToXml not working

Hi,
    I have added the following code in OpcConfirmOrder()

var ordersToExport = new List<Order>() ;

ordersToExport.AddRange(_orderService.GetOrdersByIds(new int[] { placeOrderResult.PlacedOrder.Id }).Where(HasAccessToOrder));
                    
ICacheManager cacheManager = EngineContext.Current.ContainerManager.Resolve<ICacheManager>("nop_cache_static");
IStoreService _storeService = EngineContext.Current.Resolve<IStoreService>();
ICategoryService _categoryService = EngineContext.Current.Resolve<ICategoryService>();
IManufacturerService _manufacturerService = MockRepository.GenerateMock<IManufacturerService>();
ICustomerService _customerService = EngineContext.Current.Resolve<ICustomerService>();
IProductAttributeService _productAttributeService = EngineContext.Current.Resolve<IProductAttributeService>();
IPictureService _pictureService = EngineContext.Current.Resolve<IPictureService>();
INewsLetterSubscriptionService _newsLetterSubscriptionService = EngineContext.Current.Resolve<INewsLetterSubscriptionService>();

ProductEditorSettings _productEditorSettings = new ProductEditorSettings();
IVendorService _vendorService = EngineContext.Current.Resolve<IVendorService>();
IProductTemplateService _productTemplateService = EngineContext.Current.Resolve<IProductTemplateService>();
IDateRangeService _dateRangeService = EngineContext.Current.Resolve<IDateRangeService>();
ITaxCategoryService _taxCategoryService = EngineContext.Current.Resolve<ITaxCategoryService>();
IMeasureService _measureService = EngineContext.Current.Resolve<IMeasureService>();
CatalogSettings _catalogSettings = new CatalogSettings();
IGenericAttributeService _genericAttributeService = EngineContext.Current.Resolve<IGenericAttributeService>();

ICustomerAttributeFormatter _customerAttributeFormatter = EngineContext.Current.Resolve<ICustomerAttributeFormatter>();

ExportManager exportManager = new ExportManager(_categoryService, _manufacturerService, _customerService,
                                                _productAttributeService,
                                                _pictureService, _newsLetterSubscriptionService,
                                                _storeService, _workContext, _productEditorSettings,
                                                _vendorService, _productTemplateService, _dateRangeService,
                                                _taxCategoryService, _measureService, _catalogSettings,
                                                _genericAttributeService, _customerAttributeFormatter,
                                                _orderSettings);

                    
try {

    var xml = exportManager.ExportOrdersToXml(ordersToExport);
    XmlDownloadResult xmlResult = new XmlDownloadResult(xml, "orders.xml");
    xmlResult.ExecuteResult(this.ControllerContext);

    }
    
catch (Exception exc) {
    ErrorNotification(exc);
    }

I have added the above code immediately after:

var placeOrderResult = _orderProcessingService.PlaceOrder(processPaymentRequest);

                if (placeOrderResult.Success)
                {
                    

                    _httpContext.Session["OrderPaymentInfo"] = null;
                    var postProcessPaymentRequest = new PostProcessPaymentRequest
                    {
                        Order = placeOrderResult.PlacedOrder
                    };


The code runs through but there is no orders.xml file.  Also, I have noticed that when this code is executed from the Export Selected Orders to Xml Menu item in Administration,

[HttpPost]
        public virtual ActionResult ExportXmlSelected(string selectedIds)
        {
            if (!_permissionService.Authorize(StandardPermissionProvider.ManageOrders))
                return AccessDeniedView();
            
            var orders = new List<Order>();
            if (selectedIds != null)
            {
                var ids = selectedIds
                    .Split(new [] { ',' }, StringSplitOptions.RemoveEmptyEntries)
                    .Select(x => Convert.ToInt32(x))
                    .ToArray();
                orders.AddRange(_orderService.GetOrdersByIds(ids).Where(HasAccessToOrder));
            }

            var xml = _exportManager.ExportOrdersToXml(orders);
            return new XmlDownloadResult(xml, "orders.xml");
        }

the orders list that is passed to _exportManager.ExportOrdersToXml(orders) ; has the type:

System.Data.Entity.DynamicProxies.Order  where as the code I have put in OpcConfirmOrder() , the ordersToExport list passed to exportManager.ExportOrdersToXml(orders) has the type Nop.Core.Domain.Orders.Order  .

Does this make a difference?

Also, I was not sure how to instantiate _manufacturerService so I instantiated it with MockRepository.  I don't know if this makes a difference or not.
