Description Paul Webster

I was investigating (what is now :-)  Bug 255984 trying to remove some root features. After the restart/Apply now I can still see them, so I thought I'd try and use Reset... to go back to a known config from before.  It NPEd.

Comment 2 Susan McCourt

Fixed in HEAD >20090112.
This was a problem with the metadata repository element code.  The revert code was moved to new core support that doesn't require a rollback repository on 20090107, so it was not possible to hit this problem using revert in current builds.

However I was able to verify that the problem from the duplicate bug still existed and that this fixes the problem.
