Sorting does not work stably when committing a nested ListView on every current object change

Hello Christian,
I think that it would be best if you grabbed the example code from the standard XAF controller:

C#
public class ListViewAutoCommitController2 : ViewController {  
    private void ObjectSpace_ObjectEndEdit(Object sender, ObjectManipulatingEventArgs e) {  
        // B37305  
        if (ObjectSpace.ModifiedObjects.Contains(e.Object)) {  
            // B33747  
            CommitChanges();  
        }  
    }  
    private void ListView_Closing(object sender, EventArgs e) {  
        CommitChanges();  
    }  
    private void ListView_QueryCanChangeCurrentObject(object sender, CancelEventArgs e) {  
        CommitChanges();  
    }  
    private void ListView_ValidateObject(object sender, ValidateObjectEventArgs e) {  
        // B32035  
        CommitChanges();  
    }  
    protected virtual void CommitChanges() {  
        // B33150  
        if (!ObjectSpace.IsDeleting && (ObjectSpace.ModifiedObjects.Count > 0)) {  
            ObjectSpace.CommitChanges();  
        }  
    }  
    protected override void OnActivated() {  
        base.OnActivated();  
        ObjectSpace.ObjectEndEdit += new EventHandler<ObjectManipulatingEventArgs>(ObjectSpace_ObjectEndEdit);  
        ListView listView = (ListView)View;  
        listView.Closing += new EventHandler(ListView_Closing);  
        listView.QueryCanChangeCurrentObject += new EventHandler<CancelEventArgs>(ListView_QueryCanChangeCurrentObject);  
        listView.ValidateObject += new EventHandler<ValidateObjectEventArgs>(ListView_ValidateObject);  
    }  
    protected override void OnDeactivated() {  
        base.OnDeactivated();  
        ObjectSpace.ObjectEndEdit -= new EventHandler<ObjectManipulatingEventArgs>(ObjectSpace_ObjectEndEdit);  
        ListView listView = (ListView)View;  
        listView.Closing -= new EventHandler(ListView_Closing);  
        listView.QueryCanChangeCurrentObject -= new EventHandler<CancelEventArgs>(ListView_QueryCanChangeCurrentObject);  
        listView.ValidateObject -= new EventHandler<ValidateObjectEventArgs>(ListView_ValidateObject);  
    }  
    protected virtual void InitializeComponent() { }  
    public ListViewAutoCommitController2()  
        : base() {  
        InitializeComponent();  
        TargetViewNesting = Nesting.Nested;  
        TypeOfView = typeof(ListView);  
    }  
}  

I have just changed its TargetViewNesting property. Unless I missed something, it all worked fine in your scenario.
