When Setting Repository Group To Blank Repo Group Wont Be Moved To Root
- Create a repo group inside another repo group.
- Attempt to move it back to root by selecting the blank record as the group parent.
It's fairly easy to fix by hand (set parent ID to null, configure it's path, move the folder), so there isn't really a big risk if you run into this for the time being, just a minor inconvenience.
Also haven't found any other issues reported about this, so I'm assuming it wasn't snuck into trunk.
