    I'm starting to use these chart controls to make some reports at work, and I've stumbled onto a weird bug, where I get a KeyNotFoundException when I attempt to update the Series.ItemsSource property. I've also noticed I see the same exception in your WPF version of ChartBuilder when you set the 1st series as a PieSeries and drag the number of series left and right. Any ideas where that comes from? I've worked around this problem in my code by re-creating the PieSeries instead of just updating its ItemsSource, but I wish I had a simpler solution.

    abrien, I've been debugging this and I know why the exception happens in WPF Charting. For some reason that I don't understand yet, the DataPoint.State DependencyProperty is not getting updated when it should and so the DataPoints are all in the wrong states and code that assumes certain invariants ends up being wrong and throwing the exception you see. This may sound familiar - I believe it's exactly the same problem I call out in my post about new/old DataPoints not showing/hiding correctly. Okay, so this is good to know and I'll track down what's going wrong on WPF that the State property isn't behaving properly. So now I've got one very important question for you: In YOUR scenario are you using WPF Charting or Silverlight Charting? If you're using WPF Charting, then we know the problem and I'll sort it out more on Monday and hopefully give you a fix and sorry, but I did warn you that WPF Charting is completely untested. :) HOWEVER, if you're using Silverlight Charting and seeing this problem, then I would very much like to understand your scenario better because I doubt it's the same exact issue and it's seeming like something we've never seen before. (As you probably know, your ChartBuilder scenario works just fine for on Silverlight.) If you could please get back to me with the answer, I'd very much appreciate it! If it turns out to be a problem with Silverlight Charting, then I'll work with you to try to come up with a simplified demonstration of the problem that I'll be able to run and debug myself. Thank you very much for reporting this issue!

    Update: Soon after turning off the computer, I figured out why the DependencyProperty isn't getting updated. I should be able to fix the WPF Charting issue on Monday and will post a new DLL. So the big remaining question is whether anyone is seeing this behavior with Silverlight Charting...
