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?
