Struts 2: Iterator/Valuestack question.

So, I have a
with an iterator. The iterator iterates through a List of ReservationBeans.
Each bean contains a couple of values, the date of the reservation is one of them.
The list contains several ReservationBeans, some of the beans have the same date value.
Ex. There are two ReservationsBeans where the value of date is "2009-03-03".
If the iterator has already iterated a ReservationBean with the same date as the current ReservationBean I want it to ignore further instructions. This would be done with an <s:if> tag.
<s:iterator value="res"> <s:if test="the current date != the previous date"> //Do something. </s:if> </s:iterator>
So my question is, is there a way of collecting the date value of the previous ReservationBean from the value stack?
Or do you have any other clever ideas on how this could be achieved?

Save it with <s:set...>?
I agree. Here's the link:
