Markus, Could you svn up, rebuild and try again. I think I've fixed it but since this is not code I know well (it's just been added by Artem) I haven't tested my change. I'm not even sure the Query Manager is working at all since the issue isn't closed: http://jira.xwiki.org/jira/browse/XWIKI-2444 Artem, could you please let us know the status?
