688163 - Mid-air collision not detected in Firefox if page is refreshed while displaying "old" version of bug

Status: RESOLVED DUPLICATE of bug 437212

(Bugzilla :: Creating/Changing Bugs, defect)

Description

[Kent Rogers [:mrbball]]

User Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.22) Gecko/20110906 Fedora/3.6.22-1.fc14 Firefox/3.6.22
Build ID: 20110906122925

Steps to reproduce:

I am running Firefox 3.6.22 on Fedora 14 and I reproduce this problem as
follows:

1. Open the same bug (show_bug.cgi) in two different browser tabs
2. In first tab change a field (e.g. severity) and click "Save Changes"
3. In second tab (which is now out of date), hit Ctrl-R or the refresh
   button.
4. In second tab add a comment and click "Save Changes".


Actual results:

Step #3 above causes the value of delta_ts in the form to get updated to
the value from the DB, but the value of severity remains at the "old"
value.  Then, step #4 does not result in a mid-air collision and the
severity is unknowingly reset to its original value.

This problem can be quite severe, depending on the circumstances.  If
fields like priority/severity are unknowingly lowered (and then not
caught), it can lead to high priority/severity bugs NOT triggering
certain actions and falling through the cracks.


Expected results:

I also tried this on Chrome (14.0), Safari (5.1), and IE8 and in all of
those browsers I saw the behavior I expected: when I did the refresh in
the second tab (step #3), ALL values were refreshed from the DB.

[:glob ✱]

This is not a bug in Bugzilla but the way Firefox works. Refreshing doesn't override values currently displayed in single-select fields.
