Custom Shipping Provider GetPrice Delivery trouble

Delford Chaffin asked on February 4, 2016 22:06

I'm trying to follow this example to create a custom shipping provider:

https://docs.kentico.com/display/K9/Example+-+Creating+a+shipping+carrier+provider+with+costs+based+on+the+country

In my GetPrice method, every time I try to get the delivery address values, they are blank. For example:

System.Text.StringBuilder msg = new System.Text.StringBuilder();
msg.AppendFormat("AddressLine1: {0}", delivery.DeliveryAddress.AddressLine1);
msg.AppendFormat("<br />AddressLine2: {0}", delivery.DeliveryAddress.AddressLine2);
msg.AppendFormat("<br />AddressCity: {0}", delivery.DeliveryAddress.AddressCity);
msg.AppendFormat("<br />AddressState: {0}", delivery.DeliveryAddress.GetStateCode());
msg.AppendFormat("<br />AddressCountry: {0}", delivery.DeliveryAddress.GetCountryTwoLetterCode());
msg.AppendFormat("<br />AddressZip: {0}", delivery.DeliveryAddress.AddressZip);
EventLogProvider.LogInformation("FedExCarrierProvider", "GetPrice", msg.ToString());

... this shows the following in the EventLog:

AddressLine1: 
AddressLine2: 
AddressCity: 
AddressState: WV
AddressCountry: US
AddressZip:

I cannot make the other fields load. I've tried delivery.DeliveryAddress.SetAddress() to no avail (I'm not really sure what that does).

Thanks

For anyone else that runs into this issue, I ended up moving the addresses to a separate, earlier page and now the CustomCarrierProvider's GetPrice() method now has the address information. In other words, I didn't really "solve" the problem, I just worked around it. But it does seem like some kind of bug at this point to me.

Most likely there is an AddressID which will be populated. Just create your AddressInfo object based on that ID and use that instead.

AddressInfo addr = AddressInfoProvider.GetAddressInfo(delivery.addressid);

Not sure what object exactly delivery is, but there should be an addressid, either on that object or on the delivery.DeliveryAddress object.

Adding:

AddressInfo addr = AddressInfoProvider.GetAddressInfo(delivery.DeliveryAddress.AddressID);

... and trying to write out that gives me the infamous: "Message: Object reference not set to an instance of an object."

Is there any place in your delivery object that you can get the addressID, What class is delivery using or based on?

See the link in the original question. The Delivery class is CMS.Ecommerce.Delivery and is in the signature of the GetPrice method in the ICarrierProvider interface.

namespace CMS.Ecommerce
{
    // Summary:
    //     Class representing a delivery (bunch of items shipped together using a shipping
    //     option).
    public sealed class Delivery
    {
        public Delivery();

        // Summary:
        //     Custom data.
        public IDataContainer CustomData { get; internal set; }
        //
        // Summary:
        //     Address where delivery is shipped to.
        public IAddress DeliveryAddress { get; internal set; }
        //
        // Summary:
        //     Items shipped in this delivery. Only products and accessory product options
        //     are present.
        public IEnumerable<DeliveryItem> Items { get; internal set; }
        //
        // Summary:
        //     The date of shipping (package departure from store).
        public DateTime ShippingDate { get; internal set; }
        //
        // Summary:
        //     Shipping option used to deliver this delivery.
        public ShippingOptionInfo ShippingOption { get; internal set; }
        //
        // Summary:
        //     Weight of whole package.
        public decimal Weight { get; internal set; }
    }
}

In my GetPrice method, I can get the delivery Weight and Items and from the DeliveryAddress, I can call GetStateCode() and GetCountryTwoLetterCode(). The other properties of DeliveryAddress I cannot get to populate from the form on the page.
