title: How to programmatically evaluate EL in a managed bean
body: <p>I would like to add a simple template language to my application based on Seam / JSF to let the users compose their own email.</p>
  
  <p>Since I don't want to create a new parser, I would like to use the Unified Expression Language   setting the context all by myself. </p>
  
  <p>How can I do that?</p>
