Implementing OptimizedControllersCreation

When I implement the new XAF feature" OptimizedControllersCreation = true";
public PatTracWindowsFormsApplication() {
InitializeComponent();
this.OptimizedControllersCreation = true;

I get the following error when navigating tabs in detail view;

System.NullReferenceException: Object reference not set to an instance of an object.

when I remove it everything works fine. This seems like a feature that I would like to have implemented and working.

Thanks,
