Primefaces 3.4.2 javascript error - jsf-2

Question

I'm developing a web application using the 3.4.2 version of Primefaces. I have a p:pickList on it. Application is working using a general template and each page replaces the general_content of the template, which is being reloaded for every request. My problem is that the picklist is not working (cannot interact with it) because some JavaScript error happens when I load the page. This is my xhtml:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:p="http://primefaces.org/ui"
template="/templates/general_template.xhtml">
<ui:define name="metadata">
<f:metadata>
<f:viewParam id="user" name="user"
value="#{navegableUserData._ParamUser}" />
<f:viewParam id="NavIndex" name="NavIndex"
value="#{navegableUserData._QueueIndex}" />
<f:event type="preRenderView"
listener="#{navegableUserData.initialize}" />
</f:metadata>
<h:message for="user" />
</ui:define>
<ui:define name="general_content">
<h:form id="SystemUserForm">
<p:pickList id="rolePickList" value="#{navegableUserData._ListRoles}"
var="role" itemValue="#{role}" converter="rolConverter">
<f:facet name="sourceCaption">
<h:outputText value="#{msg.AVAILABLE}" />
</f:facet>
<f:facet name="targetCaption">
<h:outputText value="#{msg.ASSIGNED}" />
</f:facet>
<p:column>
<h:outputText value="#{role._Nombre}" />
</p:column>
</p:pickList>
</h:form>
</ui:define>
This is the JavaScript error I have:
Firebug in Firefox
Firebug is telling me the element 'a' cannot be found in the first line of primefaces.js
"a is undefined"
PrimeFaces={escapeClientId:function(a){return"#"+a.replace(/:/g,"\\:")},
...
Inspector in Chrome
Uncaught TypeError: Cannot call method 'replace' of undefined primefaces.js.xhtml:1

It looks like some jquery is failing. With the previous version of Prime, 3.4.1, everything is working fine.

p:pickList (primefaces v3.4.2) requires itemLabel to be specified.
Just add
itemLabel="#{role}"
to your p:pickList
