title: GWT i18n, change metaTag and reload application
body: <p>I'm trying to internationalize my GWT application.</p>
  
  <p>I read the tutorials and see some examples.</p>
  
  <p>Is there a way to do the language change without adding the url the tag "?locale=de"</p>
  
  <p>My objective is at the menu login screen, the user selects the languague, and then it reloads.
  I managed to do that with the adding of the locale to the url.[Ugly way to me]</p>
  
  <p>I was reading that there is possible with meta tags in Html file.
  So i tryed to put that in the html file
           </p>
  
  <p>It loads in that language, but i can't change no more the language.</p>
  
  <p>Is possible to chage the language only using meta tags?</p>
  
  <p>In code, i can read and chage the meta tag value but when i refresh the change i made is lost</p>
  
  <pre><code>    NodeList&lt;Element&gt; tags = Document.get().getElementsByTagName("meta");
      for (int i = 0; i &lt; tags.getLength(); i++) {
          MetaElement metaTag = ((MetaElement) tags.getItem(i));
          System.out.println("metaTag.getName() = " + metaTag.getName());
          System.out.println("metaTag.getContent = " + metaTag.getContent());
          if (metaTag.getName().equals("gwt:property")) {
              metaTag.setContent("locale=de");
          }
      }
      Window.Location.reload();
  </code></pre>
