[RhinoCommon] Options pages with child pages - dialog gets stuck

@menno wrote:

We have some options pages that have child pages, and I notice that once a child page is selected, navigation gets stuck and no other pages can be selected. A minimal reproduction of this error is found here (adapted from the Samples from GitHub). The SampleCsOptionsParentPage is registered in the OnLoad method of the plugin.

How do I properly register a child options page? In Rhino-5 the method below works.

internal class SampleCsOptionsParentPage : OptionsDialogPage
{
  private UserControl m_control;

  public SampleCsOptionsParentPage()
    : base("Sample-Parent")
  {
    Children.Add(new SampleCsOptionsChildPage());
  }

  public override object PageControl
  {
    get { return m_control ?? (m_control = new UserControl()); }
  }

  public override bool OnApply()
  {
    RhinoApp.WriteLine("SampleCsOptionsParentPage.OnApply");
    return true;
  }

  public override void OnCancel()
  {
    RhinoApp.WriteLine("SampleCsOptionsParentPage.OnCancel");
  }
}

internal class SampleCsOptionsChildPage : StackedDialogPage
{
  private SampleCsOptionsUserControl m_control;

  public SampleCsOptionsChildPage()
    : base("Sample-Child")
  {
  }

  public override object PageControl
  {
    get { return m_control ?? (m_control = new SampleCsOptionsUserControl()); }
  }

  public override bool OnApply()
  {
    RhinoApp.WriteLine("SampleCsOptionsChildPage.OnApply");
    return true;
  }

  public override void OnCancel()
  {
    RhinoApp.WriteLine("SampleCsOptionsChildPage.OnCancel");
  }
}
