title: Filtering list of beans with expression
body: <p>I have a list of beans and I would like to get a sub list matching a criteria on one or several properties with an expression as below:</p>
  
  <pre><code>${data[propertyName=='my value']}
  </code></pre>
  
  <p>data is a list of beans that have a property called propertyName.</p>
  
  <p>Is such approach possible? If not, what is the best approach to do that.</p>
  
  <p>Thanks very much for your answers.
