They are indeed lists :-) But I've not a clear idea yet about what is list, what an array, what a collection, what any sort of collection... Please, could you provide me a good reference to keep trying to understand what I feel like a must to leverage the power of Velocity and, of course, the nice team XWiki/Velocity? These two lists come from a for you well known lines of code. Something like this... #set ($xwqlquery = "where doc.translation = 0 and doc.creationDate < '2013-01-01' and doc.parent like '%$doc.title%' and doc.fullName NOT IN ($nicestr0) order by doc.object(XWiki.XWikiUsers).last_name") #set ($results = $services.query.xwql($xwqlquery).execute()) Please, is it possible to check $results if is it a list? For instance, I guessed it is a list because I can apply size() to it. Is this a right guess?
