Seam 1.2.1 enhanced EL

[skot]

:(

Have to downgrade my project to Seam 1.2.1 in order to run in JBoss 4.0.4.

Slowly getting things to work, but I don't seem to have enhanced EL. When I try to use parameters with an EL method expression, it chokes like this:

---
12:00:17,624 ERROR [STDERR] Aug 12, 2008 12:00:17 PM com.sun.facelets.FaceletViewHandler handleRenderException
SEVERE: Error Rendering View[/play/profile.xhtml]

        ...
Caused by: com.sun.el.parser.ParseException: Encountered "(" at line 1, column 22.
Was expecting one of:
    "}" ...
    ...
---

Looking at the complete stack trace (pasted below), it doesn't seem like org.jboss.seam.ui.facelet.SeamFaceletViewHandler is getting involved at all.

My web.xml and faces-config.xml are just as seam-gen made them: with the SeamFaceletViewHandler loaded by ajax4jsf:

--- (web.xml)
    <context-param>
        <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
        <param-value>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</param-value>
    </context-param>
---

--- (faces-config.xml)
   <application>
      <message-bundle>messages</message-bundle>
      <!-- Disabled when using Ajax4JSF
      <view-handler>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</view-handler>
      -->
   </application>
---

But I've also tried it the other way around, commenting out all the ajax stuff in web.xml and uncommenting-out the view-handler tag in faces-config.xml. No luck.

Can anyone think of something else I need to do to get enhanced EL going in Seam 1.2.1?

Sorry to ask about an older version...

Were you not able to upgrade JBoss 4.0.4 to JSF 1.2 RI so you can run Seam 2?

[skot]

No, the client is running JBoss 4.0.4 with Tomcat 5.5. And according to the seam2migration.txt,

- Tomcat 5.5 is not compatible with JSF 1.2

The client is a large corporation and I don't get to make changes to their server configuration.

But Seam EL should work with JSF 1.1, right?

[charliepower76]

I'm not 100% sure, but I think Seam EL enhancements where introduced with version 2.0. I don't think it's possible to make it work with version 1.x

[charliepower76]

Sorry, were introduced :)

[svadu]

I had a application working with the El enhancements under Seam 1.x under Caucho Resin. I've successfully migrated the application to Seam 2.0 with minimal problems.

[sjmenden]

yeah, I was thinking 4.0.5, sorry about that, from the seam2migration.txt:

Seam 2.0 has been tested on the following containers:

* JBoss 4.2 (it is possible to run Seam2 on JBoss 4.0.5 by upgrading JSF)
ect...

[skot]

No, Seam 1.2.1 is supposed to support enhanced EL. See the Seam 1.2.1 reference Chapter 25: Expression language enhancements.

[charliepower76]

My mistake, sorry !

[andrzejurban]

I'm experiencing the same problem as you have. I also have to migrate my seam2 application to 1.2.1 version. Have you managed to solve this issue?

I'd be grateful for your help,

Regards,
Andrzej Urban

[skot]

Never figured it out. Sorry.
