Using a dialog window to select a name and directory to save the file

Question

Hi there
I have a problem with the FILE_SAVE_DIALOG method or better with the windows that will be shown.
Before I save a file (e.g. PDF file) on the presentation server (the PC), I want to open a dialog window to have the option to give another directory and file name, under which I will save the file.
Therefore I use the method CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG. I found many information about this FILE_SAVE_DIALOG in this forum, but these tips didn't satisfy me.
The main problem is the FILE_FILTER. How to use this filter (is it a STRING?) properly, when I want to have a list in the dialog window? Nothing worked till now.
I use ERP 2005 with JAVA 1.4.1-07.
My Code:
DATA: fileName         TYPE  STRING,
      path             TYPE  STRING,
      workdir          TYPE  STRING,
      user_action      TYPE  I,
      encoding         TYPE  ABAP_ENCODING.
    fileName = I_FILENAME.
    path = I_PATH.
    CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
       EXPORTING
         WINDOW_TITLE         = 'Save Adobe PDF file'
*         WITH_ENCODING        = 'X'
         INITIAL_DIRECTORY    = workdir
*         DEFAULT_EXTENSION    = '*.pdf'
         DEFAULT_FILE_NAME    = fileName
         FILE_FILTER          = '*.pdf'
         PROMPT_ON_OVERWRITE  = 'X'
      CHANGING
         FILENAME             = fileName
         PATH                 = path
         FULLPATH             = fullpath
         USER_ACTION          = user_action
         FILE_ENCODING        = encoding
      EXCEPTIONS
         CNTL_ERROR           = 1
         ERROR_NO_GUI         = 2
         NOT_SUPPORTED_BY_GUI = 3
         others               = 4.
    IF SY-SUBRC <> 0.
      EXIT.
    ENDIF.
    IF user_action <> CL_GUI_FRONTEND_SERVICES=>ACTION_OK.
      EXIT.
    ENDIF.
When I call this method with these parameters, I get the dialog window, but there is no filtering for PDFs.
I also tried the ideas with:
  FILE_FILTER = 'Adobe files (*.pdf)|(*.pdf)'
and so on. But nothing made the dialog window work properly, even the selection list didn't show the right content to select.
Who can help with this method SAVE_FILE_DIALOG?
Thanks

       path type string,
       file_path type string.
data: itab type standard table of cskt.
start-of-selection.
  SELECT * FROM cskt INTO TABLE itab.
  call method cl_gui_frontend_services=>file_save_dialog
      exporting
                FILE_FILTER = '*.PDF'
      changing FILENAME = file
               path     = path
               fullpath = file_path.
  check not file_path is initial.
  call method cl_gui_frontend_services=>gui_download
    exporting    filename                = file_Path
                  WRITE_FIELD_SEPARATOR = 'X'
     changing    data_tab                = itab.
