92376 - [DUP]history fails to remember selected option.

Status: RESOLVED DUPLICATE of bug 95622

(Core :: DOM: Navigation, defect)

Description

[Stephane Saux]

Reproducible: always.
Using build 07202001.0.9.2, but pretty much anything will do.

To reproduce:

Go to the bugzilla query page.
Select:
product: PSM
target-milestone 2.1
submit.
hit the back button.
The target-milestone is not remembered.

Notes:
4.7X handles that just fine.
I suspect that two things might play a role in the session history being lost in 
this case. One is that by selecting PSM, the page javascript changes the 
available options for the target-milestone. The other is that when the js does 
that, it redraws the select boxes shape as well as the content (4.7X only 
changes the options and keeps whatever size the select box had when the first 
was first loaded).

Forgetting this type of session information is bad because:
For most select boxes (the one that were not redrawn by js) the selection is 
remembered, so the user is unsuspecting that for some the selection is 
forgotten, and the result of the second submit is likely to be wrong. The 
selection forgotten could very well have been "Do not charge me $1000"

cc'ing pollmann. This may need work in the backend restoration code, which
should probably take care of such dynamic things.

Rod has a bug that this is a duplicate of, handing to him...

If I remember correctly, Rod came up with a patch, but nearly any approach for
fixing this problem has potentially dangerous side effects.

If options are dynamically added or removed we don't remember the it

This is a dup

Is this futured just b/c you think it's a dupe? Or are we really not going to
fix this bug. I can't find the dupe...

Dupe of bug 83033, which was a bug in bugzilla. That bug has since been fixed,
but mozilla is still broken - see bug 125421

[John Levon]

This bug is stale and should be resolved as fixed/dupe, afaics ??

Comment 7

[Dave]

It seems like Bug 95622 might be the best one to dupe this bug against.  If that
issue is fixed, then the query page as it currently exists will work fine.  If
not, there's also also Bug 153074.
