title: Is it possible to use <c:if> inside <a4j:repeat>
body: <p>Is it possible to use <code>&lt;c:if&gt;</code> inside <code>&lt;a4j:repeat&gt;</code>?</p>
  
  <p>I need to render a <code>&lt;br /&gt;</code> each 4 elements. I tried the following approach:</p>
  
  <pre><code>&lt;a4j:repeat value="#{MBean.sucursal.events}" var="item" rowKeyVar="idx" &gt;   
     &lt;h:outputText value="#{item.eventDescription}" id="item1" /&gt;
     &lt;c: if test=#{idx % 4 == 0}&gt;
         &lt;br /&gt;
     &lt;/c:if&gt;
  &lt;/a4j:repeat&gt;
  </code></pre>
  
  <p>However, it does not render the <code>&lt;br /&gt;</code> elements at all. </p>
  
  <p>How can I achieve the requirement anyway?</p>
