I need to hop out for 3 hours, but I have committed my best guess at a fix for the GAL-68 client/server ordering mismatch problem to https://source.sakaiproject.org/contrib/ucb/image-gallery/branches/GAL-68 I haven't had time to check that this does anything other than build unfortunately, but hopefully it will be edifying to study and perhaps kick around until I get back... Cheers, Antranig.
