             Summary: [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


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.
