[Zope] Choice of the sorting key of a dtml-in tag

Hi again, I'd like to make a page with a list of my Zclass instances and to be able to sort them by different key. I tryed with this code : <dtml-if "REQUEST.has_key('skey')"> <dtml-else> <dtml-call "REQUEST.set('skey', 'bobobase_modification_time reverse')"> </dtml-if> <dtml-in "objectValues(['article'])" size=3 sort=skey start=query_start> But it doesn't work : instances are not sorted correctly... Any idea ?
