No changes to save error message

Question

Hello All,
I am using Oracle forms and db 10g. I want to have more than one forms simultaneously open. When I save a record in the third form I get a "No changes to save" error message twice. I know that the error comes from the other two forms. I tried to set the error message level to a higher value but I still get the error message.
So my question is :
Can I get rid of the "no changes to save" error message while having more than one form opened at the same time.

have a look at this solution http://talk2gerd.blogspot.com/2006/12/best-practices-on-error-and-on-message.html
snippet:
DECLARE
  V_Error_Code       NUMBER;
  V_Error_Text       VARCHAR2 (2000);
  V_DBMS_Error_Code  NUMBER;
  V_DBMS_Error_Text  VARCHAR2 (2000);
BEGIN
  V_Error_Code      := Error_Code;
  V_Error_Text      := Error_Text;
V_DBMS_Error_Code := DBMS_Error_Code;
  V_DBMS_Error_Text := DBMS_Error_Text;
  IF V_Error_Code IN (40401, 40405) THEN
    || 40401, 40405 - no changes to save / apply  get filtered
    NULL;
  ELSIF V_Error_Code IN (-1034, -3114) THEN
    || -1034, -3114 - not connected to database
    Message ('Not connect to database, exiting Form');
    Exit_Form (no_validate);
  ELSIF V_Error_Code IN (40508, 40735)
  AND   V_DBMS_Error_Code BETWEEN -20999 AND -20000 THEN
    || -20000 errors are raised by RAISE_APPLICATION_ERROR
    || They are handled in a different way
    Show_and_Log_DB_Error (V_DBMS_Error_Text);
  ELSE
    || All other errors went into Show_and_Log_Error, where they
    || get inspected, analyzed and logged.
    Show_and_Log_Error (V_Error_Code);
  END IF;
END;
