Hi Team!

I'm having the following exception throwed sometimes (I can't reproduce it consistently).

Is this a bug?

Hello Leticia,

We cannot confirm whether or not this is a bug unless we have a project that demonstrates this. We cannot get all the information we need just from a stack trace. If you need further assistance with this, I will ask that you provide us with a small working project that reproduces the error, so that we can take a look.

As I mentioned in another ticket of yours earlier today, we suggest you do not use the old RadChart for new development, but use the new RadChartView.
