title: No more toggle event from p:columntoggler since PF6
body: <p>we had the following snippet working perfectly in PF5.x:</p>
  
  <pre><code>&lt;p:commandButton styleClass="columntoggler" id="toggler" type="button" value="Toggler" icon=""/&gt;
  &lt;p:columnToggler datasource="personTable"  trigger="toggler"&gt;
   &lt;p:ajax event="toggle" listener="#{listPersonsBean.onToggleListPersons}" update=""  process="@(form)"/&gt;
  &lt;/p:columnToggler&gt;
  </code></pre>
  
  <p>Since we switched to PF6 the listener doesn't get called anymore. Does anybody have an idea why?</p>
