    Exeption  - trying to write to file, using CSVWriter.

      I have got the following exception:

      Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
      at application.utils.GestureGuideLogger.logExcel(GestureGuideLogger.java

      the row code is:

           238:     writerExcel.writeNext(new String[]{buffer.toString()});

      same happens, if I write instead:


      //messageExcel is "String[]" as well.

      What is wrong?
