Comment:
Confirming the issue still is presenting itself in django 1.2 with Chrome
13.0.782.220. As stated by CollinAnderson, both halfs of this issue are
easily reproduced 100% of the time using user permissions.
1. If you use navigation other than save from a user change page and then
hit your back button you will find all permissions for that user will be
cleared. Refreshing the change page will restore the list to it's correct
values. However, if you save without doing that you will remove all
previously added permissions.
2. If you save a user change page (with or without making any changes) and
then hit the back button the user permissions with have the first n
permissions in the list.
This is a pretty nasty bug in the sneaky way it screws up your data. It's
very easy to miss while making edits in the admin and could completely
screw things up. This effect all many to many relationships (although
obviously user permissions is a easy example)
