title: commandLink don't put a link on screen
body: <p>i'm starting with jsf and i'm having a issue with this project.</p>
  
  <p>The following command don't create a link that i need to go to the next page, only give me "Novo usuário" written on the screen:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
      &lt;html xmlns="http://www.w3.org/1999/xhtml"
          xmlns:h="http://xmlns.jcp.org/jsf/html"
          xmlns:f="http://xmlns.jcp.org/jsf/core"&gt;
      &lt;h:head&gt;
          &lt;title&gt;Financeiro&lt;/title&gt;
      &lt;/h:head&gt;
      &lt;h:body&gt;
          &lt;h1&gt;Financeiro&lt;/h1&gt;
          &lt;h:form&gt;
              &lt;h:commandLink action="#{usuarioBean.novo}"&gt;Novo Usuário&lt;/h:commandLink&gt;    
          &lt;/h:form&gt;
      &lt;/h:body&gt;
      &lt;/html&gt;
  </code></pre>
  
  <p>I also tried this variation, without success:</p>
  
  <pre><code>&lt;h:commandLink action="#{usuarioBean.novo}" value="Novo usuário"/&gt;
  </code></pre>
  
  <p>This is the method called by <code>#{usuarioBean.novo}</code></p>
  
  <pre><code>public class UsuarioBean {
      private Usuario usuario = new Usuario();
      private String confirmarSenha;
  
      public String novo() { 
          this.usuario = new Usuario();
          this.usuario.setAtivo(true);
          return "/publico/usuario"; 
      }
  }
  </code></pre>
  
  <p>P.S. i'm br, so i'm sorry in advance for my english</p>
