I'm trying to replace parts of a string in a JSP file in Alfresco (you can find it there).
More specifically, I want to display more information after the "fullName" on line 54. The information I need is stored in r.id as a string of the form "GROUP_something", where I want the "something". I can display the r.id without issues, as in the snippet below, but as soon as I try to use fn:replace to remove the GROUP_ prefix then it breaks down.
Original:
<h:outputText id="user-txt" value="#{r.fullName}" rendered="#{r.isGroup}" />
Works as well:
<h:outputText id="user-txt" value="#{r.fullName} (#{r.id})" rendered="#{r.isGroup}" />
Not working:
<h:outputText id="user-txt" value="#{r.fullName} (#{fn:replace(r.id, 'GROUP_', '')})" rendered="#{r.isGroup}" />

I can't understand this error, as other answers (eg this one or this one) advocate this exact method.
I also added the function taglib:
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
in the header.
Any help appreciated!
Edit: more info about the environment: I'm using the "bundle" version of Alfresco, using Tomcat 7.0.30 as a container. The following versions of the libraries are used:
- JSF Apache MyFaces v1.1.8 (myfaces-api-1.1.8.jar and myfaces-impl-1.1.8.jar)
- JSP Tomcat's built-in Jasper (jasper.jar)
- EL I think it's Tomcat's built-in Jasper-EL (through el-api.jar and jasper-el.jar), although Alfresco also bundles commons-el.jar (with Specification-Version: 2.0 and Implementation-Version: 1.0)
