External Selection - Githubissues

Hey,

i am trying to highlight a selected element in the drawingcontrol3D, but selected from external. So i have a list with all spaces of the model, when i select a space an event is triggered

using (var model = IfcStore.Open(filePathIFC1)) {

            var selectedSpace = model.Instances.OfType<IIfcSpace>().Where(p => p.Name.ToString() == entityID).FirstOrDefault() as IPersistEntity;

            SelectedElement = selectedSpace;

            DrawingControl.ReloadModel(DrawingControl3D.ModelRefreshOptions.ViewPreserveCameraPosition);
        }

From the XBim git WPFSample i have this code parts

public static readonly DependencyProperty ModelProviderProperty = DependencyProperty.Register("ModelProvider", typeof(ObjectDataProvider), typeof(MainWindow));

    private ObjectDataProvider ModelProvider
    {
        get
        {
            return MainFrame.DataContext as ObjectDataProvider;
        }
    }

    #endregion

    public IfcStore Model
    {
        get { return ModelProvider.ObjectInstance as IfcStore; }
    }

    void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {
        ModelProvider.Refresh();
    }

    public IPersistEntity SelectedElement
    {
        get => DrawingControl.SelectedEntity;
        set => DrawingControl.SelectedEntity = value;
    }

    public Xbim.Presentation.DrawingControl3D.SelectionBehaviours SelectionBehaviour
    {
        get => DrawingControl.SelectionBehaviour;
        set => DrawingControl.SelectionBehaviour = value;
    }

    public Xbim.Presentation.EntitySelection Selection
    {
        get => DrawingControl.Selection;
        set => DrawingControl.Selection = value;
    }

    public delegate void SelectionChangedHandler(object sender, System.Windows.Controls.SelectionChangedEventArgs e);

    public event SelectionChangedEventHandler SelectionChanged;

    private void LoadXbimFile(string dlgFileName)
    {
        Clear();

        var model = IfcStore.Open(dlgFileName);
        var context = new Xbim3DModelContext(model);
        context.CreateContext();
        ModelProvider.ObjectInstance = model;

    }

The drawingcontrol3D is working fine, and highlight "OnSelectionChanged" is working fine inside the view. But i can't trigger onselectionchanged from external like in my first code part above. I mean i can, and everything is working... but the selected space is not highlightes afterwarts.

Thx for the help.

oh and this is my xaml
