Description Anton Sharapov 2008-08-17 04:34:56 UTC 
This is the exception that occurs when I try to add row on sheet after sheet.groupRow(...) method :
java.lang.ClassCastException: org.apache.poi.hssf.record.aggregates.ColumnInfoRecordsAggregate
	at org.apache.poi.hssf.model.Sheet.addRow(Sheet.java:769)
	at org.apache.poi.hssf.usermodel.HSSFSheet.addRow(HSSFSheet.java:298)
	at org.apache.poi.hssf.usermodel.HSSFSheet.createRow(HSSFSheet.java:201)

example code: 
        final HSSFWorkbook wb = new HSSFWorkbook();
        final HSSFSheet sheet = wb.createSheet("test");
        sheet.createRow(0);
        sheet.createRow(1);
        sheet.groupRow(0,1);
        sheet.createRow(2);

Tested on current poi version (poi-3.2-alpha1-20080817)
Note: in earlier builds (checked on poi-3.2-alpha1-20080716) this bug wasn't occurs.
