Hi,<br><br>To check the length of a Box object use:<br><br>when<br><div style="margin-left: 40px;">$box : Box(length == 10)<br></div>then<br><div style="margin-left: 40px;">...<br></div><br>There are two ways to iterate over your list depending the version you are using. Assuming BoxList has a property boxes returning a collection. In 
3.0.5 you can use:<br><br>when<br><div style="margin-left: 40px;">BoxList($b : boxes)<br></div>then<br><div style="margin-left: 40px;">for(Iterator it = $b.iterator();it.hasNext();) {<br><div style="margin-left: 40px;">assert(
it.next());<br></div>}<br></div>end<br><br>On trunk you can use the from keyword to combine the iteration and the rule<br><br>when<br><div style="margin-left: 40px;">$list : BoxList()<br></div><div style="margin-left: 40px;">
$box : Box(length == 10) from $list.getBoxes()<br></div>then<br><div style="margin-left: 40px;">...<br></div><br>cheers<br>Steve<br><br><div>
