Data binding SelectedObject

I might be missing the boat but I think you might have a bug with Data binding SelectedObject.  The behavior can be reproduced with slight changes to sample app QuickStart SelectedObject.  Add this to SelectedObject.xaml:

        <Button Grid.Row="3" HorizontalAlignment="Left" Margin="105,26,0,10"
                Name="button1" Width="75" Click="button1_Click"
                Content="{Binding Alice}"/>

And make SelectedObject.xaml.cs look like this:

-------------

using Mindscape.WpfPropertyGrid.SampleData;
using System.Windows.Controls;

namespace QuickStart
{
  /// <summary>
  /// Interaction logic for SelectedObject.xaml
  /// </summary>
  public partial class SelectedObject : Page
  {
     class Persons : Observable {
        private Person alice;
        public Person Alice {
           get { return alice; }
           set { Set<Person>(ref alice, value, "Alice"); }
        }
        private Person bob;
        public Person Bob {
           get { return bob; }
           set { Set<Person>(ref bob, value, "Bob"); }
        }
     }

     Persons Foo;

    public SelectedObject()
    {
      InitializeComponent();

      #region Attaching the Person object

      TestGrid.SelectedObject = Person.Alice;

      #endregion

      Foo=new Persons();
      Foo.Alice=Person.Alice;
      Foo.Bob=Person.Bob;
      DataContext = Foo;
    }

    private void button1_Click(object sender, System.Windows.RoutedEventArgs e)
    {
       if (Foo.Alice==null) Foo.Alice=Person.Alice; else Foo.Alice=null;
    }
  }
}
-------------

When I run this and click the button, the button's text always displays the expected value, but the PropertyGrid only shows Alice once and then is blank from there on out.

Thanks for reporting this.  This was a bug in 2.0 which has since been fixed.  If you grab the latest nightly build (retail edition from the store, trial edition from the Downloads page) then you should find that it is now working -- let us know if not.
