New Post: AvalonDock loses control state in Release V2.3.0

Hi,

I tried buliding a small app to reproduce the issue in v2.3, but with no success.
Here's the XAML I used :

<xcad:DockingManager x:Name="AvalonDockingManager" 
                              DocumentsSource="{Binding Workspaces, Mode=TwoWay}">
            <xcad:DockingManager.Theme>
               <xcad:VS2010Theme />
            </xcad:DockingManager.Theme>
            <xcad:DockingManager.LayoutItemContainerStyle>
               <Style TargetType="{x:Type xcad:LayoutItem}">
                  <Setter Property="Title"
                          Value="{Binding Model.Tag}" />
               </Style>
            </xcad:DockingManager.LayoutItemContainerStyle>
 </xcad:DockingManager>

Here's the CodeBehind I used :

public partial class MainWindow : Window
  {
    public MainWindow()
    {
      InitializeComponent();

      AvalonDockingManager.DataContext = this;

      this.Workspaces = new ObservableCollection<object>()
      {
        new Button() { Content = "My Button", Tag = "The Button"},
        new TextBox() { Text = "My TextBox", Tag = "The TextBox"},
        new DataGridControl() { Tag = "The DataGrid", ItemsSource = new List<MyData>(){  new MyData() { Age = 12, FirstName = "Tom", LastName = "AAA"},
                                                                                          new MyData() { Age = 45, FirstName = "Kevin", LastName = "BBB"},
                                                                                          new MyData() { Age = 58, FirstName = "Julie", LastName = "CCC"},
                                                                                          new MyData() { Age = 66, FirstName = "Vicki", LastName = "DDD"},
                                                                                          new MyData() { Age = 25, FirstName = "Simon", LastName = "EEE"},
                                                                                        } 
                       }
      };
    }

    public ObservableCollection<object> Workspaces
    {
      get;
      set;
    }
  }

  public class MyData
  {
    public string FirstName
    {
      get;
      set;
    }
    public string LastName
    {
      get;
      set;
    }
    public int Age
    {
      get;
      set;
    }
  }

In addition, I don't have the warnings for unfound resourceKeys. I have search the 4 you mentionned in the solution, but they can't be found in the Toolkit v2.3. Are they associated to your app ?
