Add new groups and users in RC4

Hello All, I try to switch from rc2 to rc4 and notice a strange beahivor in rc4. I checked out the source and built the war, deployed it, set the superadmin pw, imported the rc4.xar from the xwiki.org site. when i try to add new groups or new users, the process succeeds, i.e. the new groups / users *are* created, but they do not apear in the groups/users list in the admin space. Has any of you encountered the same problem?
