Import-export of a document with an unsupported "Of Pie" chart (ofPieChart) results in an invalid document.

Add support for "Of Pie" charts (ofPieChart).

trying to open the attached workbook with this code:

Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
using (Stream input = File.OpenRead("sample.xlsx"))
{
  var provider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();
  // The import method enables you to also pass a byte[] with the XLSX document data
  workbook = provider.Import(input, TimeSpan.FromSeconds(30));
}

I get an unhandled exception:

An unhandled exception of type 'System.ArgumentNullException' occurred in Telerik.Documents.Spreadsheet.dll
Value cannot be null.

Any idea what's going on?

Thank you for your time,

 

Phil
