title: Use static methods in EL
body: <p>I'm facing a strange problem here with EL.</p>
  
  <p>I just wanted to use <a href="http://docs.oracle.com/javase/8/docs/api/java/lang/String.html#join-java.lang.CharSequence-java.lang.CharSequence...-" rel="nofollow noreferrer">String.join()</a> in EL but it is not working.</p>
  
  <pre><code>#{String.join(',', myList)}
  </code></pre>
  
  <p>This is not doing anything in JSF except prevent my page to load. I know i can do this with <code>&lt;ui:repeat&gt;</code> but i need to use it in EL expression.</p>
  
  <p>Any ideas ?</p>
