Sparkline will throw NullPointerException when insertRows

Workbook wb = new Workbook("c:/aspose/SparkInsertRows.xlsx");
Workbook newWb = new Workbook();
newWb.copy(wb);
newWb.getWorksheets().get(0).getCells().insertRows(6, 2);



Exception in thread "main" java.lang.NullPointerException

I use cells-8.2.0.1

Hi,


Thanks for providing us template file and sample code.

After an initial test, I observed the issue as you mentioned by using your sample code with your template file. I got the exception:
Exception in thread “main” java.lang.NullPointerException
at com.aspose.cells.Sparkline.a(Unknown Source)
at com.aspose.cells.SparklineCollection.a(Unknown Source)
at com.aspose.cells.SparklineGroup.a(Unknown Source)
at com.aspose.cells.SparklineGroupCollection.a(Unknown Source)
at com.aspose.cells.Cells.a(Unknown Source)

e.g
Sample code:

Workbook wb = new Workbook(“SparkInsertRows.xlsx”);
Workbook newWb = new Workbook();
newWb.copy(wb);
newWb.getWorksheets().get(0).getCells().insertRows(6, 2);
