Bug in internal build: 2010.3.1331.40

[Arnstein]

Hi, we're getting this exception when updating to v. 2010.3.1331.40 in the RadGridView control:
 
System.Reflection.TargetInvocationException was unhandled
  Message=Property accessor 'C' on object 'RadControlsWpfApp2.A' threw the following exception:'Object does not match target type.'

It seems like the problem is related to the number of sublevels in the DataMemberBinding. In the example below the binding of the first column works, but the second column fails.

To recreate the exception:

<Window x:Class="RadControlsWpfApp2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView" 
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <telerik:RadGridView
            ItemsSource="{Binding Items}"
            AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=B.Id}" Header="Works" ></telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=B.C.Name}" Header="Fails" ></telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

namespace RadControlsWpfApp2
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            var model = new Model();
            DataContext = model;
        }
    }
}

using System.Collections.Generic;
 
namespace RadControlsWpfApp2
{
    class Model
    {
        public Model()
        {
            Items = new List<A> {new A(), new A()};
        }
        public IList<A> Items { get; set; }
    }
 
    class A
    {
        public A()
        {
            B = new B();
        }
        public B B { get; set; }
    }
    class B
    {
        public B()
        {
            C = new C();
            Id = "3213123";
        }
 
        public string Id { get; set; }
        public C C { get; set; }
    }
    class C
    {
        public C()
        {
            Name = "Test";
        }
        public string Name { get; set; }
    }
}
