Use JSTL forEach loop's varStatus as an ID

The variable set by varStatus is a LoopTagStatus object, not an int. Use:

<div id="divIDNo${theCount.index}">

To clarify:

${theCount.index} starts counting at 0 unless you've set the begin attribute

${theCount.count} starts counting at 1

---

you'd use any of these:

JSTL c:forEach varStatus properties

Property Getter Description

current getCurrent() The item (from the collection) for the current round of iteration.

index getIndex() The zero-based index for the current round of iteration.

count getCount() The one-based count for the current round of iteration

first isFirst() Flag indicating whether the current round is the first pass through the iteration

last isLast() Flag indicating whether the current round is the last pass through the iteration

begin getBegin() The value of the begin attribute

end getEnd() The value of the end attribute

step getStep() The value of the step attribute

---

You can try this. similar result

 <c:forEach items="${loopableObject}" var="theObject" varStatus="theCount">
    <div id="divIDNo${theCount.count}"></div>
 </c:forEach>

Its really helped me to dynamically generate ids of showDetailItem for the below code.

<af:forEach id="fe1" items="#{viewScope.bean.tranTypeList}" var="ttf" varStatus="ttfVs" > 
<af:showDetailItem  id ="divIDNo${ttfVs.count}" text="#{ttf.trandef}"......>

if you execute this line <af:outputText value="#{ttfVs}"/> prints the below:

{index=3, count=4, last=false, first=false, end=8, step=1, begin=0}
