[shale] Add getMessage() method to AbstractViewController?

[Richard Wallace]

Hello everyone,

I have a simple feature request.  Can we get a method added to the 
AbstractViewController class that gets a message out of the applications 
configured message bundle?  Something as simple as:

   protected String getMessage (String messageKey) {
       ResourceBundle rb = ResourceBundle.getBundle (getApplication 
().getMessageBundle (), getFacesContext ().getViewRoot ().getLocale ());
       return rb.getString (messageKey);
   }

Something that might also be useful is one that takes an optional 
Object[] as parameters and then uses MessageFormat to format the message:

   protected String getMessage (String messageKey, Object[] params) {
       String messageBundleName = getApplication ().getMessageBundle ();
       Locale locale = getFacesContext ().getViewRoot ().getLocale ();
       ResourceBundle rb = ResourceBundle.getBundle (messageBundleName, 
locale);
       String msgPattern = rb.getString (messageKey);
       String message;
       if (params != null) {
           message = MessageFormat.format (msgPattern, params);
       } else {
           message = msgPattern;
       }
       return message;
   }


I've found this to be of tremendous help in simplifying error handling 
code, or when I want to display a success message or something like 
that.  It makes things so much cleaner.


What do you think?

Thanks,
Rich
