How to use an IterateTag on an Enumerated value (eg session attributes/values) [struts 1.1RC2]

[Brook, Andy]

Hi all,
 
I've been trying to provide a non-scriptlet solution to describing
attributes and values in a session as part of a 'pretty debug page'
using the iterate tag.  
 
It seems we need to use commons-IteratorUtils (Deprecated. Use
commons-collections' IteratorUtils.asIterator(Enumeration).)  Though how
to do that in a nice tag is interesting in itself.
 
Also, Id like to *get* the value of an attribute during the iterate but
keep coming unstuck with nesting problems, is this even possible?
 
Scriptlet version (works)
 
<BR><BR><B>Session attributes</B></BR>
<%
java.util.Enumeration e = session.getAttributeNames();
String key;
 
while (e.hasMoreElements())
{
      key=(String)e.nextElement();  
      out.println("<BR>key="+key+",
value="+session.getAttribute(key).toString());
}
%>
 
 
Nice taglib version (broken)
<logic:iterate id="item" collection="session.attributeNames"
type="java.lang.String">
        <BR><bean:write name="item"/> &nbsp;
        <% out.println(session.getAttribute((String)item)); %>
</logic:iterate>
 
 
Any idea/pointers appreciated,
 
Andy.
