title: JSF EL and + or condition
body: <p>What would be the best way to format the following condition as in EL?</p>
  
  <pre><code>#{bean.booleanValue and (bean.stringValue ne 'MYCLOSED' or bean.stringValue ne 'ALLCLOSED')}"
  </code></pre>
  
  <p>The brackets don't seem to be recognised as a valid expression but it is a requirement that the statement logically render as follows:</p>
  
  <pre><code>bean.booleanValue &amp;&amp; (bean.stringValue != 'MYCLOSED' || bean.stringValue != 'ALLCLOSED')
  </code></pre>
