nested:iterate id attribute doesn't work

           Summary: nested:iterate id attribute doesn't work
           Product: Struts
           Version: 1.1 Beta 2
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: james.krygowski@shaws.com


I'm trying to use the id attribute on nested:iterate to expose the current 
iteration element for use as a PageContext JSP bean.  I've coded the following 
example to demonstrate the problem:

 	<nested:iterate id="element" indexId="currentIndex"
 property="theBean">
 	   <logic:present name="element">
             <%=element.hashCode()%><br>
          </logic:present>
 	   <nested:write property="name"/><br>
 	   <%=currentIndex.intValue()%>

 	</nested:iterate>

 The following code runs and outputs just the value of the name
 and the current index number.  If I removed the logic:present, I
 get a runtime error because element is null.  I think this should
 work, but it doesn't.

I traced into the nested iterate class and found that the id is always being 
removed from the page context.  

	if (iterator.hasNext()) {
	    Object element = iterator.next();
            if (element == null)
                pageContext.removeAttribute(id);
            else
                pageContext.setAttribute(id, element);
	    lengthCount++;
            started = true;
            if (indexId != null)
                pageContext.setAttribute(indexId, new Integer(getIndex()));
	    return (EVAL_BODY_TAG);
        } else
            return (SKIP_BODY);

element is always null (even though stuff is rendering on my JSP) so the id
is always getting pulled out of the pageContext.  But index id keeps getting
set.  This is pretty confusing and seems to be a bug.  Is it?
