title: Send an extra parameter through p:ajax with PrimeFaces 3.3.1 (JSF 2.0)
body: <p>is there any way to send extra parameters with p:ajax?</p>
  
  <p>I got this:</p>
  
  <pre><code>&lt;p:selectOneMenu id="crit"&gt;
      &lt;f:selectItem itemLabel="Select one..." itemValue="0" /&gt;
      &lt;f:selectItems itemLabel="#{cat.desc}" itemValue="#{cat.id}" value="#{CatBean.cats}" var="cat" /&gt;
      &lt;p:ajax event="change" listener="#{ConsBean.proccesCatSelection}" process="crit" update=":list,:crits" /&gt;
  &lt;/p:selectOneMenu&gt;
  </code></pre>
  
  <p>I need to send an ID with the event "change" but it seems to send only an AjaxBehaviorEvent.</p>
  
  <p>Thanks a lot for the attention.</p>
