I've recently upgraded to Q1 2010. In my code I have had a radchart bound to an observablecollection. The first display of the chart works fine, however when I use either collection.Clear() or ItemsSource = null I receive the following error:
|Unable to cast object of type 'System.Windows.Style' to type 'System.Collections.Generic.IList'1[System.Windows.Style]
This occurs when using a BarSeriesDefinition, however when I use a LineSeriesDefinition it works fine. Also, this used to work previously in both SeriesDefinitions.
