big problem! The following methods produce flaky results at best: XWikiGroupService gService = context.getWiki().getGroupService(context); boolean groupHasUser = gService.getAllGroupsNamesForMember(user, 100, 0, context).contains("XWiki."+PORTAL_GROUP_NAME); boolean userInGroup = gService.getAllMatchedMembersNamesForGroup("XWiki."+PORTAL_GROUP_NAME, null, 1000000, 0, true, context).contains(user); many times, both calls suggest that the user is not in the group! Even if he is! Which means that the user is added to the group many, many times! The first call to gService is the most unreliable, but I would prefer it to the second call, since we're talking a potential 10.000 users or more. I don't want to lug around collections with 10k+ objects just to check if the user is in the group?

Hi, from the hints I managed to cobble together a piece of code that works. Another problem was presented by the multithreading that happened when a user opened several iFrames containing XWiki pages at the same time. This led to the weird behaviour of stuff changing while I was processing the user.
