Hello, I desperately seek help with adding a custom payment service to UCommerce. It seem to see my DLL fine with Payments.cshtml script, my entry is as follows:

<!-- Moneris (Canada) --> <component id="Moneris" service="UCommerce.Transactions.Payments.IPaymentMethodService, UCommerce" type="uCommerceMoneris.MonerisPurchase, uCommerceMoneris" />

However during checkout when i choose the only payment method available that is setup (Moneris, my custom service I added to the backend). I get this error:

Error Loading Razor Script (file: uCommerce Payment) Object reference not set to an instance of an object.    at uCommerceMoneris.MonerisPurchase.CreatePayment(PaymentRequest request)

This is my DLL with the class which implements IPaymentFactory, IPaymentMethodService for the service:

namespace uCommerceMoneris

{

    public class MonerisPurchase : IPaymentFactory, IPaymentMethodService

    {

        public string Name { get; set; }

 

        ///

 

 

 

        /// Creates a new payment fully initialized

        ///

 

 

 

        ///

        ///

        public Payment CreatePayment(PaymentRequest request)

        {

            PurchaseOrder order = request.PurchaseOrder;

 

            var payment = new Payment

            {

                TransactionId = Guid.NewGuid().ToString(),

                PaymentMethodName = request.Payment.PaymentMethodName,

                Created = DateTime.Now,

                Fee = CalculatePaymentFee(request).Value,

                FeePercentage = request.PaymentMethod.FeePercent,

                Amount = request.Amount.Value

            };

 

            return payment;

        }

 

Does annyone have any ideas what's going on here? I've seen similar issues and tried everything I've found in the forums to no avail. Version info: Umbraco 6.1.6 and uCommerce 4.0.3.13287

Thanks!
