Hi, It should work both in groovy and velocity using the list.sort() function and xwiki.getArrayList() and xwiki.getHashMap() functions Something like <% catdoc = xwiki.getDocument("Blog.Categories") list = xwiki.getArrayList() map = xwiki.getHashMap() for(cat in catdoc.getObjects("Blog.Categories")) { name = catdoc.display("name", cat) list.add(name) map.put(name, cat) } for(item in list.sort()) { cat = map.get(item) desc = catdoc.display("description", cat) println "* $item : $desc" } %> #set($catdoc = $xwiki.getDocument("Blog.Categories")) #set($list = $xwiki.getArrayList()) #set($map = $xwiki.getHashMap()) #foreach($cat in $catdoc.getObjects("Blog.Categories")) #set($name = $catdoc.display("name", $cat)) #set($ok = $list.add($name)) $map.put($name, $cat) #end #foreach($item in $list.sort()) #set($cat = $map.get($item)) #set($desc = $catdoc.display("description", $cat)) * $item : $desc" #end Ludovic [email protected] wrote:
I have a page with a number of objects, which I want to display in sorted order. I currently have code which can view all the items (the page as well as the class is "Main.Teams":
#set($teamsdoc = $xwiki.getDocument("Main.Teams")) #foreach($team in $teamsdoc.getObjects("Main.Teams")) * $team.get('name') #end
I allow users to add new teams, but they always go to the bottom of the list. However I'd like to print out them in order by the "name" property. I've tried using groovy for this, but I just can't get simple things (like printing list contents any way other than "print teams") to work. Can anyone help? Thanks ...
