Subject: AW: Error in DbfInputStream ?!

Hello,

i changed ind the readData() method in DbfInputStream the part

        if(type == DbfTableModel.TYPE_NUMERIC)
        {
          String cell = _leis.readString(length);
          record.add(c, new Double(cell));
        }
        else
        {
          String cell = _leis.readString(length);
          record.add(c, cell);
        }

to

        String cell = _leis.readString(length);
      if(type == DbfTableModel.TYPE_NUMERIC && !cell.equals( "" ) )
      { ^^^^^^^^^^^^^^^^^^^^^
        record.add(c, new Double(cell));
      }
      else
      {
        record.add(c, cell);
      }

Now it works. Could you fix this in the next release?

Yours Ruediger
