I'm sure I'm misusing the XamDockManager but need some guidance. I have the task of persisting the state of all panes and thought using SaveLayout and LoadLayout would serve the purpose.

I've created a sample application with static layout, but my real objective is to make this work in a Prism application with dynamic tabgroup and content panes. But one thing at a time.

In my sample app, on window load I'm calling SaveLayout, which returns an xml string of the saved settings. Next, I'm calling LoadLayout, passing in this xml string. I receive this error:

• The ContentPane 'Document' is supposed to be positioned as 'Document' but information for that position was not in the layout.

The referenced ContentPane is within a DocumentContentHost. Here's the XAML for the XamDockManager and its children. I can also supply the resulting XML from SaveLayout(). This XamDockManager is the only child of a XamRibbonWindow's ContentHost:

<igDock:XamDockManager x:Name="dockManager">
   <igDock:XamDockManager.Panes>
      <igDock:SplitPane x:Name="ExplorerSplit" igDock:XamDockManager.InitialLocation="DockedLeft" Width="225">
         <igDock:TabGroupPane x:Name="ExplorerPane">
            <igDock:ContentPane x:Name="Explorer" IsPinned="True" Header="Explorer" AllowInDocumentHost="False">
               <Button Content="Explorer" IsEnabled="False" />
            </igDock:ContentPane>
         </igDock:TabGroupPane>
      </igDock:SplitPane>
      <igDock:SplitPane x:Name="ListSplit" SplitterOrientation="Vertical" igDock:XamDockManager.InitialLocation="DockedTop" Height="145">
