[CLOSED] Error with fix for #832

[Argenta]

I've just implemented the fix you provided for #832 in another application and it's producing an error whether I have SingleExpand set to true or false.

The difference in this application is that I am invoking the RowExpander using a Loader

           Html.X().RowExpander().SingleExpand(true)
            .Loader(Html.X().ComponentLoader()
                .Url(Url.Action("GetGrid"))
                .Mode(LoadMode.Component)
                .LoadMask(mask => mask.ShowMask = true)
                .Params(new { id = JRawValue.From("this.record.getId()") })
            )

The Loader code is:

        public ActionResult GetGrid(string id)
        {
            int intID = int.Parse(id);
            GridPanel grid = new GridPanel
            {
                Height = 200,
                EnableColumnHide = false,
                Store = {  new Store 
                    { 
                        Model = { new Model {
                                IDProperty = "ID",
                                Fields = {
                                    new ModelField("ID"),
                                    new ModelField("DateIncurred",ModelFieldType.Date),
                                    new ModelField("Code"),
                                    new ModelField("Description"),
                                    new ModelField("PurchaseCost",ModelFieldType.Float)
                                }
                            }
                        },
                        DataSource = projects.Costs.Where(cst => cst.PaymentID == intID).Select(cst => new {cst.DateIncurred, cst.Description, cst.Category.Code, cst.PurchaseCost}).OrderByDescending(cst => cst.DateIncurred)
                    }
                },
                ColumnModel =
                {
                    Columns =  { 
                        new DateColumn { Text = "Date", DataIndex = "DateIncurred", Flex = 14, Format = "dd/MM/yyyy"},
                        new Column { Text = "Code", DataIndex = "Code", Flex = 6 },
                        new NumberColumn { Text = "Cost", DataIndex = "PurchaseCost" , Flex = 10, Format = "£#,###.00", Align = Alignment.Right },
                        new Column { Text = "Description", DataIndex = "Description", Flex = 70 }
                    }
                },
            };
            return this.ComponentConfig(grid);
        }

When I try to open the view I get this:
