In 3.0.5 you can use: when BoxList($b : boxes) then for(Iterator it = $b.iterator();it.hasNext();) { assert( it.next()); } end On trunk you can use the from keyword to combine the iteration and the rule when $list : BoxList() $box : Box(length == 10) from $list.getBoxes() then ... cheers Steve On 2/19/07, Diwakar <raja_diwakar(a)yahoo.co.in&gt; wrote: -- Steven Williams Supervising Consultant Object Consulting Office: 8615 4500 Mob: 0439 898 668 Fax: 8615 4501 stevenw(a)objectconsulting.com.au www.objectconsulting.com.au consulting | development | training | support our experience makes the difference
