[Solved] Telerik MVC Grid Command Button throwing errors.

[Stephen]

Hi,
I'm currently having trouble with my implementation of the telerik MVC grid. It works as expected on my local machine and on dev. dervers, but once deployed to production, seems to break for reasons i'm not entirely sure of.
The production server has the .Net framework 3.5 installed and the rest of my MVC application works without any issues.

Here is my current implementation of the grid: (Telerik MVC Grid 2010.3.1318)

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Grid.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<QualifiedUsers>>" %>

<asp:Content ID="QualifiedUsersGrid" ContentPlaceHolderID="MainContent" runat="server">
    <%= Html.Telerik().Grid<QualifiedUsers>()
        .Name("Grid")
        .DataKeys(keys => keys.Add(c => c.QualifiedUserId))
        .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.Text).ImageHtmlAttributes(new { style = "margin-left:0" }))
        .DataBinding(dataBinding => dataBinding.Ajax()
            .Select("_Index", "Users")
            .Insert("_Create", "Users")
            .Update("_Update", "Users"))
        .Columns(columns =>
        {
            columns.Bound(c => c.QualifiedUserId).Width(50).Filterable(false).Sortable(false);
            columns.Bound(c => c.PartnerId).Width(120);
            columns.Bound(c => c.FiscalId).Width(100);
            columns.Bound(c => c.PaymentId).Width(150).Title("GCI");
            columns.Bound(c => c.UserName).Width(300).HtmlAttributes(new { style = "text-align:left" });
            columns.Bound(c => c.Bias).Format("{0:N}").Width(120);
            columns.Bound(c => c.InnerId).Width(150);
            columns.Bound(c => c.ChangedDate).Format("{0:MM/dd/yyyy}").Width(100);
        })
        .Filterable()
        .Selectable()
        .Sortable()
        .Scrollable(scrolling => scrolling.Height(320))
        .Pageable(x => x.PageSize(10))
        .Editable(editing => editing.Mode(GridEditMode.PopUp))
        .HtmlAttributes(new { style = "margin-bottom: 1.3em" })
        .ClientEvents(events => events.OnLoad("onQualifiedUserLoad").OnEdit("onQualifiedUserEdit"))
    %>
</asp:Content>

The version above works in production but does not give me the opportunity to edit QualifiedUsers via the grid.
When i add the following code to the grid:

columns.Command(commands =>
{
       commands.Edit().ButtonType(GridButtonType.Text);
}).Width(100).Title("Commands");

The application fails, with the error below:

Anyone? I still haven't been able to figure out why this isn't working.
