I just changed several bugs at once, and the information I had in the the devel whiteboard field got wiped. The information in devel whiteboard was identical (which I doubt matters).
Without digging too deep into this right off the bat, cant you verify that this also occurs with beta2 of the new Bugzilla? https://bugzilla.redhat.com/beta2
Yeah, it sill clears the field in both bugs.
Red Hat's current Bugzilla version is 2.18. I am moving all older open bugs to this version. Any bugs against the older versions will need to be verified that they are still bugs. This will help me also to sort them better.
Red Hat Bugzilla is now using version 3.2 of the Bugzilla codebase and therefore this bug will need to be re-verified against the new release. With the updated code this bug may no longer be relevant or may have been fixed in the new code. Updating bug version to 3.2.
