WO runs from to to bottom of your page. So it should work.
A better way would be to do the calculations in appendToResponse() before you
call super. Then all will be set before the page is rendered.
If you can not do that because of your loop, you could do it in the
displayedObjects call. Or in a method that calls displayedObjects and returns
after your calculation for this item.
