70553 - [CBX]clicking on page after opening combo box tries to load directory

Status: VERIFIED DUPLICATE of bug 62753

(Core :: Layout: Form Controls, defect, P1)

Description

[Brad Nixon]

Overview Description:
open the combo box with the list of stations. Scroll over some entries, then
click somewhere blank on the page. The url in the address bar changes to
http://www.octranspo.com/mapscheds/transitway/ which results in a "Directory
Listing Denied" error

Expected behavior:
the page should not change when this happens.

Tested on:
Moz 0.8, Win2000

probably related to bug 62753

possibly, but there are differences: in that bug is selects the wrong entry 
from the list, but here what is being loaded is not an entry from the list 
(it's the directory in which each entry in the list is located)...

I've identified why this is happening. On the URL where this bug occurs, the
code for the combo box looks like this:

<select NAME="SelectURL" onChange=
"document.location.href=
document.nav.SelectURL.options[document.nav.SelectURL.selectedIndex].value"
style="font-size: 8pt; color: #003366; background-color: #FFFFCC; font-family:
Arial; font-weight: bold" size="1">
<option
SELECTED>Station ...
<option VALUE="http://www.octranspo.com/mapscheds/transitway/abbey.htm">
Abbey
(etc...)

However, another page on the same site
(http://www.octranspo.com/newt/routekey/rk_selector_first.htm) does not
demonstrate the bug. Here is its code:

<select NAME="SelectURL" onChange=
"parent.mapwindow.location.href=
document.nav.SelectURL.options[document.nav.SelectURL.selectedIndex].value"
style="font-size: 8pt; color: #003366; background-color: #FFFFCC; font-family:
Arial; font-weight: bold" size="1">
<option VALUE="http://www.octranspo.com/newt/routekey/keymap.html"
SELECTED>route ...
<option VALUE="http://www.octranspo.com/newt/routekey/keymap_1.html">
route 1
(etc...)

The difference is this second example, there is a URL attached to the first
option, whereas in the first example (where the bug occurs) there is no url
attached to that entry. You'll notice that for the second example, if you click
on the first option "(route)" then it loads that URL even though it's the same
page. IE does not. So I guess the fix for this bug is: look at the onChange code
and see where the URL for the option is pointing to. Then only if it's different
than the current page will it be loaded.

My guess is that when it rolls up the list when nothing is selected, it can't 
tell that it is a "default" selection and somehow thinks the selection has 
changed.

This might be a dup of Bug 62753.

Verified dup.

Comment 11

This can still happen in one circumstance: If you click the dropdown, mouse over
some entries, then click within the same frame, things work fine. However, if
you click the dropdown, mouse over some entries, then click in the top frame,
the "Directory Listing Denied" error pops up again. This means that either there
is a separate issue here other than bug 62753, or the fix for 62753 doesn't work
properly with framed pages.

maybe the other bug should be reopened
