title: How I choose the value that appears by default in a SelectOneMenu
body: <p>I would like that in the <code>selectItem</code>, instead of giving me a value, it would default to one of those in <code>selectItems</code> where I have 6 values. </p>
  
  <p>Let's say I want the 4 to appear, could it be done?</p>
  
  <p>my code:</p>
  
  <pre><code>&lt;div class="row group"&gt;
  &lt;h:outputLabel for="critEjec" value="#{msg['cod_ejec']}" styleClass="nombreCampo" /&gt;
  &lt;h:selectOneMenu id="critEjec" value="#{maestroSubCategoriasBean.critEjec}" styleClass="campo"&gt;
      &lt;f:selectItem itemLabel="#{msg['comunes_seleccionarTodos']}" itemValue="-1" /&gt;
      &lt;f:selectItems value="#{maestroSubCategoriasController.comboListaEjesCatalogacion}" /&gt;
      &lt;a4j:support event="onchange" action="#{maestroSubCategoriasController.llenarComboCategorias}" reRender="CategoriasPanel,mensajesPanel" ajaxSingle="true" /&gt;
  &lt;/h:selectOneMenu&gt;
  </code></pre>
  
  <p></p>
