[xwiki-users] ordering attachements not working`

Sometime ago I was given this code to add to attachmentsinline.vm #set($attachmentsMap = $util.hashMap) #foreach($a in $attachments) #set($discard = $attachmentsMap.put($a.date, $a)) #end #set($dates = $util.arrayList) #foreach($date in $attachmentsMap.keySet()) #set($discard = $dates.add($date)) #end #set($dates = $util.sort($dates)) #set($dates = $util.reverseList($dates)) #set($attachments = $util.arrayList) #foreach($date in $dates) #set($discard = $attachments.add($attachmentsMap.get($date))) #end this works fine, putting the attachments in order on my local server However, my client (running XWiki Enterprise 1.5.1.12494) reports that it doesn't show all the attachments. He has one page with about 10 attachments, only 5 of which show. If he takes the code out all the attachments are there, but not in date order which he wants. can anyone please help.
