(Forgot to add that the same is true for the bean tag as well.)

The docs for the iterator tag,
http://struts.apache.org/2.0.11.2/docs/iterator.html
has an error, IMO (apart from the unfortunate confusion over the 'id'
vs 'var' attributes, which actually apply to struts 2.1) :
It says:
var : Name used to reference the value pushed into the Value Stack
But, if I am not mistaken, the value is not 'pushed into the
ValueStack', but 'placed into the ActionContext'.
Supplying the var/id attribute doesn't remove the stack push, it just
adds the stack context reference. For example, from S2.0.11's
IteratorComponent code:
if ((iterator != null) && iterator.hasNext()) {
Object currentValue = iterator.next();
stack.push(currentValue);
String id = getId();
if ((id != null) && (currentValue != null)) {
stack.getContext().put(id, currentValue);
}
