Unless I'm mistaken the documentation (in this case in the code 
comments) is not correct.  It doesn't put it in the PageContext, it puts 
it into the context that's a part of the OGNL ValueStack.

So (I'm guessing, I haven't tested any of this) if you set var="blah" 
you should be able to use it via <s:iterator 
value="#blah">...</s:iterator> or in a scriptlet from just the 
pageContext via 
((ValueStack)(((HttpServletRequest)pageContext.getRequest()).getAttribute(Se
rvletActionContext.STRUTS_VALUESTACK_KEY))).getContext().get("blah")

If you want to promote something from the ognl context to the 
pageContext, look at the s:set tag, with scope="page".
