The iterate tag is tied to the form bean (as you can see). When the iterate tag ends via a /iterate, it calls next() in the form Bean, which is implemented (in the base form bean that evey bean extends ) and if it hasNext it goes to the top of the loop. The "trick" is to make your form Beans implement iterator.
Ted showed me this trick (and also did some coding and sugestions for webPIM). Look at the base Form Bean and note that it implements iterator.
