Hi,

I have an issue with SaveAsPurchaseOrder method. I got a cart with several Properties and try to save PurchaseOrder. The thing is that my extra properties both in IPurchaseOrder and in LineItems are lost. Please advise. 

Some code:

This is how I create a cart:

public ICart CreateOrder(Model.Create.Order request)
{
var cart = orderRepository.Value.Create(request.OrganizationId, cartName);
cart.Properties[MetaPropertiesDefinitions.Cart.CartContent.Reference] = request.Reference;
orderRepository.Value.Save(cart);
return cart;
}

Next I want to create purchase order:

var orderReference = orderRepository.Value.SaveAsPurchaseOrder(cart);

For more context, this is how I added meta fields to Purchase Order and Cart:

 public OrderMetaFieldService()
        {
            metaDataContext = OrderContext.MetaDataContext;
        }

        public MetaField CreateMetaField(string metaClassNamespace, string metaClassName, string name, 
            MetaDataType type, int length,
            bool allowNulls, bool cultureSpecific, string description = "", int decimalPrecision = 18, int decimalScale = 4)
        {
            var context = metaDataContext;

            var metaField = GetMetaField(name);

            if (metaField == null)
            {
                metaField = MetaField.Create(context,
                    metaClassNamespace,
                    name,
                    name,
                    description,
                    type,
                    length,
                    allowNulls,
                    cultureSpecific,
                    false,
                    false);
            }

            JoinField(metaField, metaClassName);
            return metaField;
        }

        private void JoinField(MetaField field, string metaClassName)
        {
            var metaClass = MetaClass.Load(metaDataContext, metaClassName);
            if (IsMetaFieldNotConnected(field, metaClass))
            {
                metaClass.AddField(field);
            }
        }

In this case, namespace is:

public static string NamespaceName = OrderContext.Current.LineItemMetaClass.Namespace;

And class name is:

public static string ClassName = OrderContext.Current.LineItemMetaClass.Name;
