In old Bugzilla, fields that one is not permitted to modify were displayed as text instead of drop-down boxes. In the new Bugzilla, all fields are drop boxes and the only way to see whether the field is read-only or not, is to try modifying it and to see whether post_bug.cgi will rehect or accept. The only advantage of the new behavior is not having to login first before modifying non-publically-modifiable fields (e.g, you can modify them first, click "Commit" and have process_bug.cgi prompt for the login info). IMHO the old behavior is better.
This is understandable. This is the way the current upstream bugzilla handles it so I am changing this to a RFE. This should be done easily enough in the templates now. I will look into this for post release.
Just a note that I will fix this but will wait til after new bugzilla goes into production.
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.
The new version 3.2 of Bugzilla will show the field as text only if the user cannot edit it.
