Why "{0}": befor message?

Question

Hi guys,
please help me with this problem.
I've create 2 methods that performs application message creating.
protected void message(String clientId,String key){
          // cerca il testo del messaggio richiesto
          String text=null;
          try{
               ResourceBundle bundle=ResourceBundle.getBundle("microarray.bundle.messageResource",getFacesContext().getViewRoot().getLocale());
               text=bundle.getString(key);
          catch(Exception e){
               text="???"+key+"???";
          getFacesContext().addMessage(clientId,new FacesMessage(text));
     /* metodo per la ricerca dei messaggi dei bean dell'applicazione, cio� i messaggi della logica*/
     protected void appMessage(String clientId,String key){
          // cerca il testo del messaggio richiesto
          String text=null;
          try{
               ResourceBundle bundle=ResourceBundle.getBundle("microarray.bundle.application",getFacesContext().getViewRoot().getLocale());
               text=bundle.getString(key);
          catch(Exception e){
               text="???"+key+"???";
          getFacesContext().addMessage(clientId,new FacesMessage(text));
     }I have 2 bundles,one for application message (like authentication),another one for text in the pages.
Message method create message in the pages, appMessage create message for the logic.
My question is:
Why when my application gives me a message, like for example User not found,it gives me in this way
"{0}":User not found!I have two bundle(application and page text), each one in 2 version, italian and english. Thanks very much

Actually, I have had the same problem.
You can override the original validation messages (that you can find in the javax.faces.Messages.properties of your myfaces lib).
Create your own validation file (for example : validation.properties) in the /src/main/ressources directory of your web application. In this file you can override the "javax.faces.component.UIInput.REQUIRED" and "javax.faces.component.UIInput.REQUIRED_detail" properties :
javax.faces.component.UIInput.REQUIRED        = Validation error
javax.faces.component.UIInput.REQUIRED_detail = This is a required field.Then, add this in your faces-config.xml to tell JSF to look in the validation.properties before looking into the original Messages.properties :
     <application>
          <message-bundle>validation</message-bundle>
     </application>(maybe I misunderstood your question and you have already done all those things... :p )
