Re: [xwiki-users] Please, badly need help with HQL...

Definitely the backlinks need to be revised in the new rendering. That's a bit hard... Rollback is not an actual rollback, like pointing back to an older version, but the old version is loaded from the history and saved as a new version. You could parse the version comment, which looks like: "Rollback to version 2.1", and extract the version from there. -- Sergiu Dumitriu http://purl.org/net/sergiu/
