Hi,
Wendy, I tried:
<c:forEach items="${PandoraForm.motTreeMap}" var="mot" >
<c:out value="${mot.key}" />
</c:forEach>
That's a test to output every key in the Map which contain 10 items.
the tags are recognized but what's output is ${mot.key} once litteraly, the
strings aren't recognized as data. I tried without the c:out but the reszult
is the same.
> So your form has two Maps that are keyed alike? I don't think you need a
> custom tag (or Struts tags) at all. This iterates over a treeMap and uses

>
> <c:forEach items="${treeMap}" var="obj" >
> ${hashMap[obj.key]}
> </c:forEach>
>
> That's with the Maps in request scope... if they're coming from the form
