Parameter in EL in s:link problem

virgo47 Nov 13, 2006 3:52 PM

Hi

I have a problem using EL with parameter in s:link tag:

<s:link id="viewProject" value="#{proj.code}" action="#{projectManager.detail(proj)}"/>

produces:
/main.xhtml @45,93 action="#{projectManager.detail(proj)}" Error Parsing: #{projectManager.detail(proj)}

But it works fine in booking demo's main page. What I missed? I tried to derive from booking, but also tried to start it from scratch and now I'm stuck and I tried to move on with this parameter. ;-)

Thank you

Virgo

Thanks Gavin... addition to faces-config.xml helped. But I'm kinda confused now. My looks like this now:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE faces-config PUBLIC
 "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
 "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

<faces-config>
 <application>
 <view-handler>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</view-handler>
 </application>

 <!-- A phase listener is needed by all Seam applications
 -->
 <lifecycle>
 <phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener>
 </lifecycle>
</faces-config>

And the one from booking demo looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config
 PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
 "http://java.sun.com/dtd/web-facesconfig_1_0.dtd">

<faces-config>

 <!-- Select one of the standard transaction models for the Seam application -->

 <lifecycle>
 <phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener>
 </lifecycle>

</faces-config>

Why you don't need that view-handler? I can't notice difference between JSF 1.0 or 1.1 in header (tried both). I had no view-handler there and it worked fine but when I started to experiment with it (after your post) it suddenly stopped to process JSF at all (browser offers download and it was raw JSF) - I can't reproduce that EL exception. ;-)

I'm glad it works now (and it even fixed my other problem), just little confused. I saw some JSF/EJB3 stuff before, but this all is overwhelming for me so far. ;-)

The booking demo uses Ajax4JSF, and Ajax4JSF has a special way to install the facelets viewhandler to avoid ordering problems (look in web.xml).

Ah, now I see... I ripped the Ajax4JSF off for the time being (too many new things at once) - so that explains everything. I see that handler thingy in web.xml now. :-)

Thanks a lot
