Thanks again.

<c:forEach> supports a "varStatus" attribute. The value of that atrribute is a
String that names an instance of javax.servlet.jsp.jstl.core.LoopTagStatus. The
LoopTagStatus instance has nested visibility so that it's only available within
the enclosing <c:forEach> tag. LoopTagStatus exposes a number of properties,
but the one you're probably interested in is "index":
..
<c:forEach var="bean" varStatus="status" items="${entry.value}">
<%-- ${status.index} is the current index --%>
...
</c:forEach>
..

How can I refer to the index of the current iteration with c:forEach
(analogous to the indexId attribute to logic:iterate)?
Thanks,
Erik

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array
as the value.
I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I
don't know what the keys are going to be or how many there will be.
Within that iteration, for each key in the keySet, I need to iterate
over the buckets of the array that is the value for that key.
To make this more clear, let's say I will produce a table of tables,
somewhat like this:
<table>
<!-- start outer iteration here; iterate over the keySet of the Map -->
<!-- Map key #0 -->
<tr>
<td>
<table>
<!-- start inner iteration #1 here; iterate over the Object[] that
is
the value for key #1 in the Map -->
<!-- Object[bucket #0] -->
<tr>
<td><!-- Object[bucket #0].property A --></td>
<td><!-- Object[bucket #0].property B --></td>
</tr>
<!-- end Object[bucket #0] -->
<!-- Object[bucket #1] -->
<tr>
<td><!-- Object[bucket #1].property A --></td>
<td><!-- Object[bucket #1].property B --></td>
</tr>
<!-- end Object[bucket #1] -->
</table>
</td>
</tr>
<!-- end Map key #0 -->
<!-- Map key #1 -->
<tr>
<td>
<table>
<!-- start inner iteration #2 here; iterate over the Object[] that
is
the value for key #2 in the Map -->
<!-- Object[bucket #0] -->
<tr>
<td><!-- Object[bucket #0].property A --></td>
<td><!-- Object[bucket #0].property B --></td>
</tr>
<!-- end Object[bucket #0] -->
<!-- Object[bucket #1] -->
<tr>
<td><!-- Object[bucket #1].property A --></td>
<td><!-- Object[bucket #1].property B --></td>
</tr>
<!-- end Object[bucket #1] -->
</table>
</td>
</tr>
<!-- end Map key #1 -->
<!-- end outer iteration -->
</table>
Could someone show me some skeleton JSTL or Struts-el code?
I would appreciate it very much,
Erik
