Re: post-redirect-get in Firefox

[Adam Hardy <ah...@cyberspaceroad.com>]

Found out how to reproduce it.

If I try over and over to submit a form, it fails several times and is 
repeatedly redisplayed with an error message. In my case "primary key is 
duplicate" because I keep forgetting to update it manually when I mess around 
like this in dev.

Since the primary key is incremented each time, on the fifth time the primary 
key reaches 5 and is valid in my DB, so it submits. This is redirected to the 
list of items, and it displays the "status saved" message.

If I then hit refresh, it does it again! The resubmit dialog shows and if I hit 
OK it hits the DB again and does another redirect and another confirmation 
status saved.

Strange one. A firefox bug probably. I'm going to upgrade to FF3 soon so I'll 
find out if the issue has been resolved.

Regards
Adam
