Seam+MyFaces+Facelets problem with EL functions

[Andrew Robinson <an...@gmail.com>]

I am having a problem with the combination of Seam 1.2.1, MyFaces
(1.1.5 or 1.2.0) and Facelets 1.1.11 when it comes to EL functions. I
am trying to get help from the facelets user list and the seam forum,
but I know a lot of myfaces users use facelets, and may have a
solution.

In MyFaces 1.1.5, EL functions work fine in the facelet views since
facelets handles those. However, with
'facesContext.getApplication().createValueBinding("#{s:hasRole('test')}");'
I get an exception.

1.1.5 error:

Caused by: javax.faces.el.ReferenceSyntaxException: Functions not
supported in expressions. Function: s:hasRole

I tried MyFaces 1.2 and got a different error.

With MyFaces Core/Api 1.2.0 I get this exception:

javax.el.ELException: Expression uses functions, but no FunctionMapper
was provided

Here is the message on the seam forum:

How can I get EL functions to work through the JSF Application object
as well as through the facelets view handler?

Thanks,
Andrew

Okay, this is still not working and is acting more confusing than
before. I'm not sure if the fault is with MyFaces 1.2 or Facelets.

I have a <t:panelNavigation2>

In it I have the following:

<t:commandNavigation2
value="#{messages.MenuBean_createCalendar}"
actionListener="#{menuBean.onMainAction}"
action="mainMenu_createCalendar"
rendered="#{s:hasRole('calendar-admin')}" />

This works just fine if it is rendered at the top level (just under
the panelNavigation2). If, I have it nested under another
commandNavigation2, and I click on the parent node so that it expands,
I get an exception that s:hasRole function does not exist.

I am quite baffled at the moment of why #{s:hasRole('calendar-admin')}
resolves just fine on an initial rendering, but not after a re-render
after a POST.

I have the following in my faces-config:

<?xml version="1.0"?>
<!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>
  <application>
    <el-resolver>org.jboss.seam.jsf.SeamELResolver</el-resolver>
  </application>
  <lifecycle>
    <phase-listener>org.jboss.seam.jsf.SeamPhaseListener</phase-listener>
  </lifecycle>
</faces-config>

Any ideas?

FYI, got it working with MyFaces 1.2 and using ValueExpression instead
of ValueBinding.

I just hope that I don't hit too many problems upgrading to MyFaces JSF 1.2
