title: How to read bean value within Renderer
body: <p>I am writing a custom jsf <code>Renderer</code> for checkboxes and radio buttons to render without <code>TABLE</code> element. My question is if I have a select box like below</p>
  
  <pre><code>    &lt;h:selectManyCheckbox id="vehicle" value="#{pageBean.vehicle}&gt;
         &lt;f:selectItems value="#{pageBean.vehiclesList} /&gt;
      &lt;/h:selectManyCheckbox&gt;
  </code></pre>
  
  <p>in the <code>encodeBegin</code> method how can I read the <code>vehiclesList</code>?</p>
