    Problem with EL method call in jboss 4.2 and facelet (newbie

    Andrew Redhead Newbie

      Hi,

      I've just got started with seam, the el and facelets (been working with ejb3 on the server side for a little while).

      Until now its all just slotted together - really good stuff :)

      However - I've come grinding to a halt trying to use the EL extensions to call a method rather than just read properties.

      In my .xhtml file I have the fragment:

      <td>
       <span class="PropValue">#{criteria.entityPropertyValue("id")}</span>
      </td>
      


      I'm using a basic jboss 4.2 installation, I've taken the faces-config.xml and web.xml from the jboss 4.2 corrected version of the seam book booking example and I don't include the el jars in my ear file. I still get the stack trace:
      javax.el.ELException: Error Parsing: #{criteria.entityPropertyValue("id")}

      Anyone got any ideas what I'm doing wrong?
