I'm trying to add a new payment option. I'm struggling A LOT because the documentation I find everywhere is from all different versions / combinations of uCommerce / Umbraco. However, my error is that I keep getting a null reference exception. I don't really know why, and I can't even say if I am using the right code examples.

So, in Payment.cshtml (this seems to work fine)

        int newPaymentMethodId;

        if (int.TryParse(HttpContext.Current.Request.Form["payment-method"], out newPaymentMethodId))

        {

            TransactionLibrary.CreatePayment(newPaymentMethodId, requestPayment:true);

            TransactionLibrary.ExecuteBasketPipeline();

            HttpContext.Current.Response.Redirect("Preview.aspx");

        }

 

My DLL

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Globalization;

using UCommerce.Infrastructure.Globalization;

using UCommerce.EntitiesV2;

using UCommerce.Transactions.Payments;

using Moneris;

 

namespace uCommerceMoneris

{

    class MonerisPurchase : IPaymentMethodService, IPaymentFactory

    {

        public string Name { get; set; }

 

        /// <summary>

        /// Creates a new payment fully initialized

        /// </summary>

        /// <param name="request"></param>

        /// <returns></returns>

        public Payment CreatePayment(PaymentRequest request)

        {

            PurchaseOrder order = request.PurchaseOrder;

            var paymentMethod = request.Payment.PaymentMethod;

            var paymentFactory = paymentMethod as IPaymentFactory;

            Payment payment = paymentFactory.CreatePayment(request);

            return payment;

        }

        public Payment RequestPayment(PaymentRequest request)

        {

            // Processing is happening synchronously so we just

            // call the backend service with ProcessPaymentRequest

            return ProcessPaymentRequest(request);

        }

 

 

        public Payment ProcessPaymentRequest(PaymentRequest request)

        {

            // Send request to remote party

 

            // Update payment according to received status from remote 

            // party, e.g. Accepted, Declined

 

 

            // Grab any transaction ids and put them on the payment before 

            // returning the Payment

            request.Payment.TransactionId = "123";

 

            return request.Payment;

 

        }

        public Payment AcquirePayment(Payment payment)

        {

            // Send request to remote party

 

            // Update payment according to received status from remote 

            // party, e.g. Accepted, Declined

 

            // Grab any transaction ids and put them on the payment before 

            // returning the Payment

            return payment;

        }

        public Payment CancelPayment(Payment payment)

        {

            // Update payment according to received status from remote 

            // party, e.g. Cancelled

 

            // Grab any transaction ids and put them on the payment before 

            // returning the Payment

            return payment;

        }

        public virtual UCommerce.Money CalculatePaymentFee(PaymentRequest request)

        {

            var order = request.PurchaseOrder;

            var paymentMethod = request.PaymentMethod;

 

            var fee = paymentMethod.GetFeeForCurrency(order.BillingCurrency);

 

            if (!order.SubTotal.HasValue)

                return new UCommerce.Money(0,

                new CultureInfo(order.CultureCode), order.BillingCurrency);

 

            return new UCommerce.Money(order.SubTotal.Value

               * (paymentMethod.FeePercent / 100)

               + fee.Fee, 

              new CultureInfo(order.CultureCode), order.BillingCurrency);

        }

    }

}

it seems that request is always NULL and I don't know why. Can someone please help me? This project is due in less than a week and I have got no where with this. At least point me to proper documentation for the latest versions of Umbraco and UCommerce regarding setting up a new payment gateway? Umbraco 6.1.6 and UCommerce version provided from the packages section.

Any help is greatly appreciated.
