title: selectOneMenu ajax events
body: <p>I am using an editable primefaces selectOneMenu to display some values. If the user selects an item from the List a textarea should be updated. However, if the user types something in the selectOneMenu, the textarea should not be updated.</p>
  
  <p>I  thought I could work this with ajax event out. However, I don't know which event I can use here. I only know the <code>valueChange</code> event. Are there any other events, like <code>onSelect</code> or <code>onKeyUp</code>?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;p:selectOneMenu id="betreff" style="width: 470px !important;"  
              editable="true" value="#{post.aktNachricht.subject}"&gt;
              &lt;p:ajax event="valueChange" update="msgtext"
                  listener="#{post.subjectSelectionChanged}" /&gt;
              &lt;f:selectItems value="#{post.subjectList}" /&gt;
  &lt;/p:selectOneMenu&gt;
  
  &lt;p:inputTextarea style="width:550px;" rows="15" id="msgtext"
          value="#{post.aktNachricht.text}" /&gt;
  </code></pre>
