HSSFSheet.setRowBreak throws NullPointerException when it's applied it on a parsed Workbook object (ie not newly created Workbook object) of an Excel file that does not have a page break already.
Created attachment 12370 [details] The test harnest program
Created attachment 12371 [details] The Excel template that works (has page break already)
Created attachment 12372 [details] The Excel template that fails (without any page break)
Works as of 12Jan2007, Testcase added. http://issues.apache.org/bugzilla/show_bug.cgi?id=41366
