Description Jennie Nguyen 2004-01-21 19:19:58 UTC
Hi,
 I am working on a workbook with Macros in it. I'm not sure if this is the 
problem. I am currently on Windows 2000, using Excel 2000. When I execute my 
code, I get "Unknown PTG" warnings, but I am not modifying or inserting any 
Formulas at all. The formula cells are left alone. When I open the workbook, I 
get a "File Error: Data may have been lost" message. Some of the cells have 
#NAME? values in them, and if I re-save the file, almost every cell that had 
values changes to either #NAME? or #REF!, and sometimes it would not allow me 
to save the file at all ("File not saved"). I don't know what I am doing wrong, 
any help is greatly appreciated! Below is the code the causes this problem: 

    //this method writes to the xsl workbook -- Gets File error when opening and
    //re-saving
    private void set_intros_values()
    {
        FileInputStream fin = null;
        FileOutputStream fout = null;
        POIFSFileSystem poifs;
        HSSFWorkbook wb;
        HSSFName hssfname;
        HSSFSheet hssfsheet;
        HSSFCell cell;
        int index = 0, i = 0;
        int rownum = 0, colnum = 0;
        String name, cell_ref = null, sheet_name = null;
        StringTokenizer st, prev_str;
        Object new_val;
        double prev;
        try {
            fin = new FileInputStream(intros_filename);
            poifs = new POIFSFileSystem(fin);
            wb = new HSSFWorkbook(poifs);

            //go through the names and see if any of the named ranges
            for (Enumeration e = name_to_vals.keys(); e.hasMoreElements();)
            {
                name = (String)e.nextElement();
                index = wb.getNameIndex(name);
                hssfname = wb.getNameAt(index);
                cell_ref = hssfname.getReference();

                    //format -- sheet_name!$col$row
                    st = new StringTokenizer(cell_ref, "$ ");
                    st.nextToken();
                    //get cell column and row
                    colnum = get_col(st.nextToken().toLowerCase());
                    rownum = Integer.valueOf(st.nextToken()).intValue() - 1;

                    //the cell to write new value to
                    hssfsheet = wb.getSheet(hssfname.getSheetName());
                    cell = (HSSFCell)(hssfsheet.getRow((short)rownum).getCell
((short)colnum));

                    new_val = name_to_vals.get(name);
                    int cell_type = cell.getCellType();
                    //check for cell type
                    switch(cell_type){
                        //Double
                        case HSSFCell.CELL_TYPE_NUMERIC:
                            cell.setCellValue(((Double)new_val).doubleValue());
                            break;

                        //Formula -- *** DO NOTHING IF FORMULA !! *****
                        case HSSFCell.CELL_TYPE_FORMULA:
                            break;
                        default:
                            break;
                    }
                }
            }
            //write out results to intros workbook
            fout = new FileOutputStream(intros_filename);
            wb.write(fout);
            fout.close();
            fin.close();
        }
        catch (Exception exc){
            exc.printStackTrace();
        }
    }

I had a similar issue.  It only arose on array formulas. I have attached the
initial excel file and the POI generated file.  The code is simply:

  POIFSFileSystem fs = 
    new POIFSFileSystem(new FileInputStream("c:\test\before.xls"));
  HSSFWorkbook wb = new HSSFWorkbook(fs);
  FileOutputStream out = 
    new FileOutputStream("c:\test\after.xls");
  wb.write( out );
  out.close();

Still have it in 3.1-beta2.
Array-Entered Formula (221h) are not yet supported and it might be a clue. The attached workbook contains a couple of such ARRAY records mixed with FORMULA records. After serialization the order if records is changed and it seems to be the problem.

Fixed in svn r690636.

POI now does round trip re-serialization of workbooks with ArrayRecords and/or TableRecords without introducing errors.

However, POI is still not able to create/edit Array or Table formulas.
