Unknown error in piechart rendering
posted

 Hello,

 

I am getting an error when rendering a piechart. This is the stacktrace of the error. I have tried to recreate the error doing exactly the same thing, but it didn't appear anymore. I still wanna know how this can happen. Does anyone have any idea's?
