Print not filled. Try to use an EmptyDataSource...!

Hi,

 

The exception message tells you exactly what is wrong.

You cannot add null values to the chart dataset and apparently one of the keys you try to put there in the pie chart is null. You should filter them out, probably by using the <filterExpression> of the dataset.

 

No wonder the keys are null if you use the empty data source implementation where all fields are null.

 

I hope this helps.
