XWQL is not tied to JCR (the execution engine is Hibernate right now). It's tied to JPQA but only at the grammar level (we have our grammer and our parser). Why do you think it's not finished? from what I've seen it looks finished and it worked well when I used it. I only saw a potential grammar issue that you are forces to use "as" for a query to be valid. For example: "from doc.object(XWiki.XWikiUsers) as user" (using "from doc.object(XWiki.XWikiUsers)" will not work) Thanks -Vincent > But yes we should really use XQL if possible. > >> >> Thanks >> -Vincent _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
