Subject: problem while implementing dependent list in HSSF



Hi all,



I am trying to implement dependent list on a column for XLS format and XLSX 
format. For this I have to use reference to another cell in same row inside the 
formula. I am using apache POI 3.7.



I am using formula as such: "=INDIRECT(UPPER($A7))" for list for 7th row 
onwards in 3rd column. I am facing weird problem. For HSSF implementation, in 
Office 2003 and office 2007, for every row, formula refers $A$7. In Office 2010 
I have not tested as of now. I want A8 to be referred for 8th row and A9 to be 
referred for 9th row and so on. In XSSF implementation, this works quite well.



The same problem I am facing for conditional formatting too.



Can someone please help? I have provided my implementation below.



Thanks in advance!

Niraj



import org.apache.poi.ss.usermodel.Sheet;

import org.apache.poi.ss.usermodel.DataValidation;

import org.apache.poi.ss.usermodel.DataValidationConstraint;

import org.apache.poi.ss.util.CellRangeAddressList;



import org.apache.poi.hssf.usermodel.DVConstraint;

import org.apache.poi.xssf.usermodel.XSSFDataValidationConstraint;



public static void addDropdown(Sheet sheet, String formula, int column, boolean 
isXSSF) {

                CellRangeAddressList cellRangeAddressList = new 
CellRangeAddressList(7, 500, column, column);

                DataValidationConstraint dvConstraint;

                If (isXSSF) {

                                dvConstraint  = new 
XSSFDataValidationConstraint(DataValidationConstraint.ValidationType.LIST, 
formula);

                } else {

                                dvConstraint = 
DVConstraint.createFormulaListConstraint(formula);

                }

                DataValidation dataValidation = 
sheet.getDataValidationHelper().createValidation(dvConstraint, 
cellRangeAddressList);

                dataValidation.setShowErrorBox(true);

}



public static void main(String[] args) {

                Sheet sheet = ... // comes from somewhere

                addDropdown(sheet, "=INDIRECT(UPPER($A7))", 2, false); // for 
hssf

                // addDropdown(sheet, "=INDIRECT(UPPER($A7))", 2, true); // for 
xssf

}
