Re: [xwiki-devs] Creating groups and adding users to them

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.
