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

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 ...
