Can't get a ListBox to work on a splash screen?...

Hi,

I download this project Prism Splash Screen Module from CodePlex and I have it working for myMEF application, but I found that only the TextBlock control works.  I can't get aListView, TextBox, ListBox, etc,. to work on the start-up splash screen.

Getting this un-explain error when I Invoke the splash screen view:

You can down load the code and try the same thing to better understand, but here is the code part:

namespace Natsar.Module.SplashScreen
{
    using System.ComponentModel.Composition;

    using Microsoft.Practices.Prism.Logging;
    using Microsoft.Practices.Prism.MefExtensions.Modularity;
    using Microsoft.Practices.Prism.Modularity;
    using Microsoft.Practices.Prism.Events;
    using Microsoft.Practices.ServiceLocation;

    using Natsar.Infrastructure.Interfaces;

    using Events;
    using Views;

    [ModuleExport(typeof(SplashScreenModule), InitializationMode = InitializationMode.OnDemand, DependsOnModuleNames = new string[] { "InfrastructureModule" })]
    public class SplashScreenModule : IModule
    {
        private IEventAggregator EventAggregator { get; set; }
        private IShell Shell { get; set; }
        private AutoResetEvent WaitForCreation { get; set; }

        [ImportingConstructor]
        public SplashScreenModule(IEventAggregator eventAggregator, IShell shell)
        {
            try
            {
                ///ArgumentNullException : need to add excpetion handling
                if (eventAggregator == null)
                {
                    throw new ArgumentNullException("eventAggregator");
                }
                if (shell == null)
                {
                    throw new ArgumentNullException("shell");
                }

                this.EventAggregator = eventAggregator;
                this.Shell = shell;
            }
            catch (Exception msg)
            {
                StringBuilder sMsg = new StringBuilder();

                sMsg.Append("Message: ").Append(msg.Message).AppendLine();
                sMsg.Append("InnerException: ").Append(msg.InnerException).AppendLine();
                sMsg.Append("Source: ").Append(msg.Source).AppendLine();
                sMsg.Append("StackTrace: ").Append(msg.StackTrace).AppendLine();

                ///TODO: Put in logic to send exception
#if (DEBUG)
                Console.WriteLine(sMsg.ToString());
                MessageBox.Show(sMsg.ToString(), this.GetType().ToString());
#endif
            }
        }

        /// <summary>
        /// Notifies the module that it has be initialized.
        /// </summary>
        public void Initialize()
        {
            Debug.WriteLine("SplashScreenModule instantiation");
            Dispatcher.CurrentDispatcher.BeginInvoke(
              (Action)(() =>
                          {
                              Shell.Show();
                              EventAggregator.GetEvent<CloseSplashEvent>().Publish(new CloseSplashEvent());
                          }));

            WaitForCreation = new AutoResetEvent(false);

            ThreadStart showSplash =
              () =>
              {
                  Dispatcher.CurrentDispatcher.BeginInvoke(
                    (Action)(() =>
                                {
                                    SplashScreenView splash = ServiceLocator.Current.GetInstance<SplashScreenView>();
                                    EventAggregator.GetEvent<CloseSplashEvent>().Subscribe(
                                      e => splash.Dispatcher.BeginInvoke((Action)splash.Close),
                                      ThreadOption.PublisherThread, true);

                                    splash.Show();

                                    WaitForCreation.Set();
                                }));

                  Dispatcher.Run();
              };

            var thread = new Thread(showSplash) { Name = "Splash Thread", IsBackground = true };
            thread.SetApartmentState(ApartmentState.STA);
            thread.Start();

            WaitForCreation.WaitOne();
        }
    }
}

I call this from my Bootstrapper.cs:

public class NatsarBootstrapper : MefBootstrapper
{

	#region Private Properties
	private IEventAggregator EventAggregator
	{
		get { return ServiceLocator.Current.GetInstance<IEventAggregator>(); }
	}
	#endregion

	protected override void InitializeModules()
	{
		IModuleManager manager = ServiceLocator.Current.GetInstance<IModuleManager>();
		manager.LoadModule("SplashScreenModule");

		EventAggregator.GetEvent<MessageUpdateEvent>().Publish(new MessageUpdateEvent { Message = "DocumentsModule" });
		manager.LoadModule("DocumentsModule");
	}
...
..
.
}

Is there anything I can do different to make this work?  What I'm doing is showing initialization messages as I load modules and data during start-up.  I want to show each message in a list instead of on a singleTextBlock, just to keep the user amusement.

I can live with the single TextBlock message, but would prefer using a ListBox.

Code is like a box of chocolates!...
