[Solved] Custom Server Binding and EF 4.1 Code First

[Hsd]

Has anyone got the MVC Grid custom server binding to work with models created using EF 4.1 Code First? I've tried modifying the MVC Grid example from the demo site (http://demos.telerik.com/aspnet-mvc/razor/grid/customserverbinding), but I get a NullReferenceException. The View is the same as the demo. The controller is below:

[GridAction(GridName = "Grid")]
public ActionResult CustomServerBinding(GridCommand command)
{
    IEnumerable data = GetServerData(!IsEmptyCommand(command) ? command : new GridCommand());
    return View(data);
}
private IEnumerable GetServerData(GridCommand command)
{
   DataLoadOptions loadOptions = new DataLoadOptions();
    loadOptions.LoadWith<Order>(o => o.Customer);
    var dataContext = new NorthwindDataContext();
    // EF 4.1 CODE FIRST GENERATED MODELS DO NOT HAVE A LOADOPTIONS
    //{
    //    LoadOptions = loadOptions
    //};
    IQueryable<Practice> data = dataContext.Order;
    //Apply filtering
    data = data.ApplyFiltering(command.FilterDescriptors);
    ViewData["total"] = data.Count();
    //Apply sorting
    data = data.ApplySorting(command.GroupDescriptors, command.SortDescriptors);
    //Apply paging
    data = data.ApplyPaging(command.Page, command.PageSize);
    //Apply grouping
    if (command.GroupDescriptors.Any())
    {
        return data.ApplyGrouping(command.GroupDescriptors);
    }
    return data.ToList();
}
private bool IsEmptyCommand(GridCommand command)
{
    return command.PageSize == 0;
}
