Error when editing cell child

[Reimund]

Hi,
I get an error 'Object does not match target type' when I want to edit a cell on  a child line. Editing the parent line works.  Same effect occors in the RadTreeListView demo after changing IsReadOnly to false.

Call stack is:
   at System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)
   at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
   at System.SecurityUtils.MethodInfoInvoke(MethodInfo method, Object target, Object[] args)
   at System.ComponentModel.ReflectPropertyDescriptor.GetValue(Object component)


XAML:
<telerik:RadTreeListView HorizontalAlignment="Left" Margin="12,12,0,0" Name="radTreeListView1" VerticalAlignment="Top" Height="209" Width="491" ItemsSource="{Binding Source={StaticResource Data}}" AutoGenerateColumns="False"  IsReadOnly="False">
            <telerik:RadTreeListView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Text}" IsReadOnly="True"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Text2}" IsReadOnly="False">
                </telerik:GridViewDataColumn>
            </telerik:RadTreeListView.Columns>
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Path=Details}" />
            </telerik:RadTreeListView.ChildTableDefinitions>
        </telerik:RadTreeListView>

Hi Reimund,

 Please try our latest service pack (or even latest internal build). We believe that this issue is already fixed.

Now I'm using 2010.3.1314.40 (WPF Q3 2010 SP 1). No improvement, same behavior as before.
