Calculate Formula --> java.lang.ArrayIndexOutOfBoundsException

Hello Aspose team,

I have been using Aspose Java for a while & of late I have been getting a lot of errors like

java.lang.ArrayIndexOutOfBoundsException: 9
at com.aspose.cells.Q.e(Unknown Source)
at com.aspose.cells.dB.t(Unknown Source)
at com.aspose.cells.dB.a(Unknown Source)
at com.aspose.cells.bI.b(Unknown Source)

at com.aspose.cells.Workbook.calculateFormula(Unknown Source)
at com.aspose.cells.Workbook.calculateFormula(Unknown Source)
at TestExcel.main(TestExcel.java:71)"

Below is my sample code

Workbook workbook = new Workbook();
Worksheet inputWorksheet = workbook.getWorksheets().getSheet(0);
System.out.println("ip file open");
Workbook dest = new Workbook();
Worksheet destWorksheet = dest.getWorksheets().getSheet(0);
dest.calculateFormula(); // Fails here
dest.save("C:\\temp\\dest.csv", FileFormatType.CSV);

I have attached the sample test & template file. Please advice.


Hello Aspose Team,

I did some investigation & found that it was working before & I have started getting error after I put the fix provided in this forum " https://forum.aspose.com/t/94706 ". When I reverted to old version it works..the new version has issues. Can we fix this to have old functionality working & unmerge option provided as well?


Thanks for your sample code and template files. Please try this fix.
