Design Time Exception

This exception occurs at design time:


Layout measurement override of element 'Controls.VirtualizingWrapPanel' should not return PositiveInfinity as its DesiredSize, even if Infinity is passed in as available size.
   at System.Windows.UIElement.Measure(Size availableSize)
   at MS.Internal.Helper.MeasureElementWithSingleChild(UIElement element, Size constraint)


My control has not really defined size (RowDefinition Height="Auto"), but if it works with the other panels, should work with this, right?


                <ListBox SelectionMode="Single" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
                            <control:VirtualizingWrapPanel />


(off) A propósito ótimo trabalho aqui, um salve para nós desenvolvedores brasileiros que utilizam WPF.
