Hi there,
I used the following code to grab an instance of HSSFPatriarch (to create a
HSSFComment in the sheet).
HSSFPatriarch patr = sheet.getDrawingPatriarch();
if (patr == null) {
patr = sheet.createDrawingPatriarch();
}
However, I get the following exception thrown from
"sheet.getDrawingPatriarch()". Does anybody have an idea of why this happening?
thanks a lot,
-david
