title: p:selectOneButton tabindex not working in primefaces 5.0
body: <p>I am using Primefaces 5.0. <br/>p:selectOneButton element is completely skipped when i tab around in the page. The code snippet is below.
  <br/>Can somebody give a hack to get the tabindex work with p:selectOneButton?</p>
  
  <pre><code>&lt;p:selectOneButton tabindex="50" id="orderAction" value="#{orderController.side}" onchange="toggleBuySell();"&gt;
      &lt;f:selectItems value="#{orderDataContainer.actionTypes}"/&gt;
      &lt;p:ajax event="change" update=" messages" process="@this " listener="#{orderController.validateAction}" oncomplete="someAction();"/&gt;
  &lt;/p:selectOneButton&gt;
  </code></pre>
