Iterate CSV in JSF

Question

How can iterate a comma seperated value in JSF without using managed beans?
For example i have an expression:
#{node.value} which will return a string "value1, value2, value3". Is there a way so i can iterate over these values?
I thought the c:forEach can work with CSV's but apperently i can't.
I tried
<c:forEach items="#{node.value}" var="val">
   <af:outputText value="#{val}"/>
</c:forEach>But i get an error "Don't know how to iterate over supplied "items" in c:forEach
I also tried with the af:forEach and that gave me the error saying that items must point to a list or array.
So... Is it possible to achieve what i want?
On a sidenote.. I don't control what's in node so i can't just change the model.
I'm using this in a template for the content presenter in webcenter. node is in fact the metadata of a document from UCM so i can't change it...

Answer 1

This means that i can't use managed beans to transform the string to an array.
I don't have access to managed bean that has access to the node.
A content presenter template looks something like this:
<?xml version = '1.0'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
          version="2.1"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
          xmlns:dt="http://xmlns.oracle.com/webcenter/content/templates"
          xmlns:h="http://java.sun.com/jsf/html">
   <dt:contentTemplateDef var="node">
        <af:outputLabel value="Field"/>
        <af:outputText value="#{node.propertyMap['xMyField'].value}"/>
  </dt:contentTemplateDef>
</jsp:root>I know need a technique so that i can iterate the CSV in node.propertyMap['xMyField'].value.
Is there a technique so i can pass the value to a managed bean? From JSF2 you can pass parameters to a method in a managed bean but ADF is not (yet) JSF2 compatible so i don't realy see a solution here.
Hope this is clear.
