[xwiki-users] livetable broken if I use MyClas.property

First I got in trouble using my own class, but even if I copy the code from the livetable macro inline documentation : #set($columns = [ "_avatar", "first_name", "last_name", "email"]) #set($columnsProperties = { "first_name" : { "type" : "text" , "size" : 10, "link" : "view"}, "last_name" : { "type" : "text" , "size" : 10, "link" : "view"}, "email" : { "type" : "text" , "size" : 20, "link" : "editor"}, "_avatar" : { "type" : "none" , "size" : 20, "link" : "none", "html" : "true", "sortable":false } }) #set($options = { "className":"XWiki.XWikiUsers", "translationPrefix" : "xe.index.users.", "tagCloud" : true, "rowCount": 15 }) #livetable("userstable" $columns $columnsProperties $options) I get a empty table. It happens in both XE 2.0 M 4 and XE 2.0 RC 1 Am I doing something wrong or is it a bug? -Rune
