How to get number of iterations in nested foreach JSTL - foreach

Question

I have a TreeMap with
<c:if test="${!empty viewObjects}">
<table border="0" cellpadding="0" cellspacing="0">
<c:forEach items="${viewObjects}" var="relations">
<c:forEach items="${relations.value}" var="role" varStatus="status">
<c:set var="subcount" value="${status.count + 1 }"/>
<tr class="color<c:out value="${subcount%2}"/>">
<td>${relations.key}</td>
<td>${role.name}</td>
</tr>
</c:forEach>
</c:forEach>
</table>
</c:if>
how can i have subcount increase with only +1 for every iteration within the nested foreach?
From what I experience "status" starts over when the first foreach iterates, so that also affects the subcount, and I will not get the total iterations.

You would do it the same way as you would do in Java: by using a counter variable initialized outside of the outermost loop:
int counter = 0;
for (...) {
for (...) {
count++;
}
}
So in JSTL, it would become
<c:set var="counter" value="0"/>
<c:forEach ...>
<c:forEach ...>
<c:set var="counter" value="${counter + 1}"/>
</c:forEach>
</c:forEach>
