TreeNavigator HierarchicalDataTemplate Template Selector Binding Comes Back Blank

I am trying to build a selector for the TreeNavigator, but when I build the HierarchicalDataTemplate outside of the TreeNavigator all the items come back blank. If I changed the Items to just DataTemplates it works just fine, but when I use HierarchicalDataTemplate it just returns a blank item with nothing in it. I know it is passing the information because I click the item and the SelectionChanged is there, and I know the Template works because it works just fine if I don't use the TemplateSelector.

This is what I do,


        <DataTemplate x:Key="CheckItem">
            <StackPanel Orientation="Horizontal">
                <CheckBox Name="cbItem" VerticalAlignment="Center" Margin="18,0,0,0"/>
                <TextBlock Text="{Binding Path=Header}" VerticalAlignment="Center" Margin="5,0,0,0"/>

        <sfp:HierarchicalDataTemplate ItemsSource="{Binding Path=Models}" x:Key="ExtendableItem">
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text="{Binding Path=Header}" VerticalAlignment="Center" Margin="18,0,0,0"/>

        <Classes:DrawerItemSelector x:Key="DrawerItemSelector" CheckableItem="{StaticResource CheckItem}" ExpandableItem="{StaticResource ExtendableItem}"/>

        <Style TargetType="sfn:SfTreeNavigatorItem">
            <Setter Property="Height" Value="53"/>
        <Style TargetType="sfn:TreeNavigatorHeaderItem">
            <Setter Property="Height" Value="50"/>
            <Setter Property="Margin" Value="0,1,0,1"/>


    <sfn:SfTreeNavigator NavigationMode="Extended" ItemsSource="{Binding}" ItemTemplateSelector="{StaticResource DrawerItemSelector}" Name="sftnTree" SelectionChanged="sftnTree_SelectionChanged"/>

Any help would be appreciated.

According to the Blog the release for Volume 4 is due on December 5th. I kind of need this working for the 2nd. Is there a work around I can use or a file I can update to get this to work?

Hello, I would like an update on Volume 4. The first week has passed and I haven't seen anywhere where I can get the update, and I really do need this fix.

Sorry for delay being caused.
