Question

Here is the property that fires PropertyChanged:

public override List<Tag> Tags
{
    get
    {
        return base.Tags;
    }
    set
    {
        if (base.Tags != value) {
            base.Tags = value;
            if (PropertyChanged != null)
            {
                PropertyChanged(this, 
                         new PropertyChangedEventArgs("Tags"));
                PropertyChanged(this, 
                         new PropertyChangedEventArgs("TotalTagPages"));
                PropertyChanged(this, 
                         new PropertyChangedEventArgs("PageHasTags"));
             }
        }

    }
}

This control refreshes correctly when CurrentPage.Tags is modified:

<TextBlock DockPanel.Dock="Bottom" Name="TagHeader" 
    Text="{Binding CurrentPage.Tags,
         Converter={converter:EnumerableToSpacedString}}"    
    Foreground="White" />

This one does NOT refresh when CurrentPage.Tags is changed, but does so when CurrentPage itself is changed:

<ListBox VerticalAlignment="Top"
   Style="{StaticResource DarkListBox}"  
   ItemTemplate="{StaticResource TagTemplateNoCounts}" 
   ItemsSource="{Binding CurrentPage.Tags}" >
        <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
        <StackPanel Orientation="Horizontal"></StackPanel>  
        </ItemsPanelTemplate>
        </ListBox.ItemsPanel>
</ListBox>

Any ideas?

Do not see any reason why that would not work (as opposed to modifying the list, which requires INotifyCollectionChanged)…
