Still waiting from the reporter what database he is using, but i can confirm this with the embedded database. It says that group is successfully created and don't let me create another, and the client shows it, but i can't see it in the groups list in the Admin Console. One have to restart Openfire to get new groups showing
Same with 3.8.1 Alpha.
Embedded database (at least)
Am I right to conclude that this issue manifests itself in the Webadmin console only? Are the new groups being using via XMPP properly?
Yes, it seems this is only the Admin Console issue. If you try to create a group with the same name again, it says it is already there. This group is also showing up in the client, so i assume xmpp is working ok.
This issue was caused by the fix for OF-278. When creating or deleting Cache entries in which group names were stored were purged, but similar cache entries where group names were stored in a paginated fashion were not purged.
Paginated cache entries are now purged when the collection of groups is modified.
