-----------------------------------------------------------
Added support for {{varStatus}}, {{begin}}, {{end}}, {{step}}, so all of the
{{c:forEach}} attributes are currently supported:
http://docs.oracle.com/javaee/5/jstl/1.1/docs/tlddocs/c/forEach.html
However when using them, you require to import {{richfaces-ui-commons}} into
the project (by default for all RichFaces components).
Example:
{code:xml}
<c:forEach items="#{this.collection}" var="item" begin="1" step="2"
varStatus="status">
#{status.isFirst()}
#{item}
</c:forEach>
{code}

> [CDK] Support "varStatus" attribute on c:forEach
> ------------------------------------------------
>
> Key: RF-12232
> URL: https://issues.jboss.org/browse/RF-12232
> Project: RichFaces
> Issue Type: Feature Request
> Security Level: Public(Everyone can see)
> Components: cdk
> Affects Versions: 4.2.1.Final
> Environment: All
> Reporter: Paul Dijou
> Assignee: Lukáš Fryč
> Labels: cdk, richfaces, xp
> Fix For: 4.3.0.Milestone1
>
>
> Right now, when using {{<c:forEach>}} tag on a CDK template.xml, you will
> have a "for" loop in Java code. There is no way to do simple logic in the
> template like knowing your current index inside the loop, etc...
> An idea would be to support the {{varStatus}} attribute from the original
> {{<c:forEach>}}. This attribute maps to the name of a bean which contains
> util methods and evolve at each iteration of the loop.
> Here is a sample:
> {code:xml}
> <c:forEach var="child" items="#{component.getChildren()}" varStatus="status">
> // Inside code
> </c:forEach>
> {code}
> Would generate something like:
> {code:java}
> LoopTagStatus status = new LoopTagStatus();
> for(UIComponent child : component.getChildren()) {
> // Inside code
> status.next();
> }
> {code}
> The javadoc of the original {{LoopTagStatus}} from JSTL is
> [here|http://docs.oracle.com/javaee/5/jstl/1.1/docs/api/javax/servlet/jsp/jstl/core/LoopTagStatus.html].
> Our LoopTagStatus would have the method and one more : the {{next()}}
> method. This one would increment the current index of the LoopTagStatus in
> order to be updated for the next iteration.
> We could also add any other usefull methods to this bean.
