Question

I have a Web Service for my ASP.NET MVC 3 app which creates a new Sales Order in AX. In AX I have created an OnlineOrder class which has 1 method for now. It is to generate a Sales Reference. Below is the code in my web service:

public AxaptaObject order;

        public void CreateOrder()
        {
            AxaptaStart();
            order = Axapta.CreateAxaptaObject("OnlineOrder");
            AxaptaStop();
        }

        public string GetSalesRef(string username, string delivery, string reference)
        {

            AxaptaStart();
            string number = order.Call("orderCreate", username, delivery, reference).ToString();
            AxaptaStop();
            return number;
        }

Then in my Controller I call these methods:

            client.CreateOrder();

            string number = client.GetSalesRef(user.Username, order.deliverymethod, order.custorder).ToString();

This doesn’t work and there is no exception info to show, its just a blank message. I believe the order AxaptaObject is not of type OnlineOrder so it can’t call those methods. How would I instantiate the object to use the orderCreate method?

EDIT:

If I do:

        public string CreateOrder(string username, string delivery, string reference)
        {
            AxaptaStart();
            order = Axapta.CreateAxaptaObject("OnlineOrder");
            string number = order.Call("orderCreate", username, delivery, reference).ToString();
            AxaptaStop();
            return number;
        }

This works, but this isn’t a valid solution as I’d like to add more methods to my OnlineOrder object in the future and I dont want to call them all in 1 method on my web service

This will never work as the order object is sort of closed when you call the AxaptaStop method.

I will suggest creating a class implementing IDisposable, then call AxaptaStop in the Dispose method. The AxaptaStart call could go to the constructor. This will allow you to scope the AX context like:

using (var axWrap = new AxWrap())
{
    var order = axWrap.onlineOrder();
    var number = axWrap.orderCreate(order, username, delivery, reference);
}

The Dispose is automatically called by the using statement.
