Error customizing validation error messages in JSF 1.2

问题

I've followed the steps answered in similar SO questions and also in other sites like Mkyong with no success. I'm describing below what I've done so far in order to customize the javax.faces.component.UIInput.REQUIRED:

1. Create MyMessages.properties in formularis.utils.missatges.custom package and customize the error:

   javax.faces.component.UIInput.REQUIRED = This value is required.
   

2. Copy MyMessages.properties and translate to my languages:

   MyMessages.properties
   MyMessages_ca_ES.properties
   MyMessages_es_ES.properties
   MyMessages_en_US.properties
   

3. Declare the properties file in faces-config:

   <application>
       <locale-config>
           <default-locale>ca_ES</default-locale>
           <supported-locale>ca_ES</supported-locale>
           <supported-locale>es_ES</supported-locale>
           <supported-locale>en_US</supported-locale>
       </locale-config>
       <message-bundle>formularis.utils.missatges.custom.MyMessages</message-bundle>
   </application>
   

Am I missing any configuration or declaration? I don't understand why my application doesn't show my custom error messages. Thank you in advance.
