title: p:selectOneRadio not updating model in event "change" with p:ajax
body: <p>I'm using an <code>p:selectOneRadio</code> with <code>p:ajax</code> and the value of another component (<code>p:inputText</code>), not binding its value in my bean.</p>
  
  <p>If I use <code>p:selectBooleanCheckbox</code> instead the behavior is exactly what I need, update the bean before calling the method in ajax. Is this a bug in <code>p:selectOneRadio</code> or is this its default behavior?</p>
  
  <p>I'm using <em>JSF2</em>, <em>PrimeFaces 4</em></p>
  
  <p>The <strong>xhtml</strong> code:</p>
  
  <pre><code> &lt;p:selectOneRadio id="enumId" value="#{xyzController.entity.enumValor}"
      disabled="#{disabled}" required="true" plain="true"&gt;
      &lt;f:selectItems value="#{xyzController.enum}" var="item"
          itemLabel="#{messages[ELUtils.evaluateExpression(itemLabelEL)]}"
          itemValue="#{item}" /&gt;
      &lt;p:ajax event="change" listener="#{xyzController.aoTrocar}"
          update="panelDominioFields" process="@form" /&gt;
  &lt;/p:selectOneRadio&gt;
  
  &lt;p:outputPanel layout="inline" id="panelDominioFields"&gt;
      &lt;p:inputText id="valorId"
          value="#{xyzController.entity.valorNumericoValido}"
          rendered="#{xyzController.mostrarCampoDominioNumerico}"
          required="true"&gt;
          &lt;f:convertNumber type="number" locale="#{localeController.locale}"
              currencyCode="#{localeController.currencyCode}" /&gt;
      &lt;/p:inputText&gt;
  &lt;/p:outputPanel&gt;
  </code></pre>
