[FIXED] [2.3] GridPanelFor throws exception when [Column(Width = 30)] specified in model

[markusn]

When I specify a column width on my model and then use the GridPanelFor helper for the model I get an exception.

Specs:
Ext.Net.Utilities 2.2.0.0 (Nuget package 2.2.1)
Ext.Net 2.2.0.41185 (Nuget Ext.Net MVC package 2.2.0)
.NET 4.5
MVC 4
Razor 2

Code:
Model

   public class Ticket
    {

        [Column(Order = 1, Width = 30)]
        public string Number { get; set; }

        [Column(Order = 2)]
        public string Status { get; set; }

        [Column(Order = 3, Flex = 1)]
        public string Subject { get; set; }

        [Column(Order = 4)]
        [Required(ErrorMessage = "Area is required")]
        [Display(Name = "Area")]
        public string Area { get; set; }
}

View

@model List<Ticket>

@(Html.X().Window()
    .ID("Tickets")
    .Closable(true)
    .Resizable(true)
    .Icon(Icon.PageCopy)
    .Title("My Tickets")
    .Draggable(true)
    .Width(500)
    .Height(300)
    .Modal(false)
    .Minimizable(true)
    .Maximizable(true)
    .Layout(LayoutType.Form)
    .Items(
        Html.X().GridPanelFor(Model)
            .ID("ticketList")
    )
)

Controller

    public class SupportController : Controller
    {

        public Ext.Net.MVC.PartialViewResult Tickets()
        {
            List<Ticket> tickets = new List<Ticket>();
            Ticket ticket = new Ticket();
            ticket.Number = "1";
            ticket.Status = "Open";
            ticket.Subject = "Bug Fix";
            ticket.Area = "Website";

            tickets.Add(ticket);
            tickets.Add(ticket);
            return new Ext.Net.MVC.PartialViewResult() { ViewName = "Tickets", Model = tickets };
        }
    }
