FacesMessage displayed two times

[Alexandre Jaquet]

Hi,

When I've some error, the error message is displayed two times with my 
code :

example :

if (validateAction() == false)
   UtilGui.setJSFErrorMessage("action_null", new Exception());       

public static void setJSFErrorMessage(String errorIdFromBundle, 
Exception fromEx) {
       if (errorIdFromBundle == null || 
errorIdFromBundle.trim().length() == 0) {
           ec.handleError("Invalid ERROR ID", ErrorLevel.FATAL);
       }
       FacesContext context = FacesContext.getCurrentInstance();
       ResourceBundle myRessourceBundle = 
ResourceBundle.getBundle("Errors", context.getViewRoot().getLocale());
       String myTranslatedString;
       try {
           myTranslatedString = 
myRessourceBundle.getString(errorIdFromBundle);
       } catch (MissingResourceException ex) {
           myTranslatedString = "[missing key '" + errorIdFromBundle + 
"' in properties file]";
       }
       context.addMessage(null, new FacesMessage(myTranslatedString));
       if (UtilGui.DEBUG_MODE && fromEx != null) {
           context.addMessage(null, new FacesMessage(fromEx.getMessage()));
           fromEx.printStackTrace();
       }
   }
any idea how to fix it ?

my best regards
