New XWiki Query Language is targets this problem. There is easy to query objects on xwql. example: If XWiki.Hidden is just a document flag: "from Document as doc, doc.object(XWiki.Hidden) as h" If not: "from Document as doc left join doc.object(XWiki.Visibility) as v where v is null or v.hidden=false" We can also introduce special syntax "doc.object?(XWiki.Visibility)" for left joins: "from Document as doc, doc.object?(XWiki.Visibility) as v where v is null or v.hidden=false" or even: "where doc.object?(XWiki.Visibility).hidden=false" -- Artem Melentyev _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
