RadSparkline - NullReferenceException when changing selected dates.

[Rob]

Hello,

I'm interested to know if anybody has encountered the following error when adjusting the selected dates on a RadTimeBar that contains a RadSparkLine?

{System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.Windows.Controls.Sparklines.DataPointsCollectionView.OnItemPropertyChanged(Object sender, PropertyChangedEventArgs e)}

I have yet to determine the exact scenario that causes the problem but will post more if I find it.
