title: Adding a language to Liferay
body: <p>I'm using Liferay Portal 6.1.0 GA1</p>
  
  <p>SCENARIO:
  After configure a portal-ext.properties like:</p>
  
  <pre><code>locales=es_ES,en_US
  time.zones=Europe/Paris
  </code></pre>
  
  <p>And running the server OK... (only those languages and timezone)</p>
  
  <p>I want to add a new language through Control Panel -> Portal Settings -> Display Settings, writting</p>
  
  <p>es_ES,en_US,it_IT to AVAILABLE LANGUAGES</p>
  
  <p>But I get:</p>
  
  <pre><code>Please enter a valid locale error. 
  </code></pre>
  
  <p>I also tried to stop LR and edit portal-ext.properties but I got the same.</p>
  
  <p>Can you help me?</p>
  
  <p>Thx a lot!
