    I have on my page a RadTransition control bind to a CollectionViewSource, which source is an ObservableCollection of ViewModels(VM) in a MVVM implementation. I use PRISM Data Template to select the right control base on the VM currently selected, here's some code snippets:
        <DataTemplate x:Key="SelectorDataTemplate" >
            <prism:DataTemplateSelector Content="{Binding}" HorizontalAlignment="Stretch"
                    VerticalAlignment="Stretch" VerticalContentAlignment="Stretch">
                            <DataTemplate x:Key="FirstViewModel">
                                    DataContext="{Binding}" />
                            <DataTemplate x:Key="SecondViewModel">

    <telerik:RadTransitionControl x:Name="navigatorMainContent"
         Content="{Binding ViewSource.View.CurrentItem}"
         ContentTemplate="{StaticResource SelectorDataTemplate}"

    Now I tried to add a RadBreadCrumb control to the interface that will allow navigate through the hierarchy. Based on the RadBreadcrumb Data binding example from the help, I change my items to be like the ExplorerItem. But now I've got this error when I try to add children to my Root item:
    You can't use both ItemTemplate and HierarchicalMemberSource.

    Is there a way to bind the breadcrumb to a flat list (as in my ObservableCollection)? Or bind my RadTransition to a HierarchicalMemberSource?

    Any help will be appreciated (I'm currently trying to reproduce this issue in an empty project to post it here).
