Hey guys,
I think this can be accomplished although not directly. I must admit it's a terrible
hack, so decide for yourself if you want to use this. I don't exactly have a test
situation, so I can't really test this, but try:
<c:forEach items="${browseForm.map.colInfoList}" begin="0" end="0" varStatus="status">
<c:out value="${status.count}"/>
</c:forEach>
This only shows the count if there is at least one item in your list, but I think you
can check for yourself whether something was printed.
Greetz,
Martin
