Status: RESOLVED WONTFIX

(Core :: DOM: Navigation, defect)

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9) Gecko/20020311
BuildID:    2002031104 (0.9.9)

Navigating a site with frames (such as the Java API documentation)
faithfully produces the page title in both the tab title and the frame
title, but the titles are incorrect in the back and forward button
history drop downs.  In fact, the *current* page title can
appear there (it shouldn't if it is a new page not visited before).


Reproducible: Always
Steps to Reproduce:
1. Start a new tab (control-t) 
2. goto http://java.sun.com/j2se/1.4/docs/api/index.html
   "Overview" appears in tab title and frame title.
3a. in lower left pane, click 1st link: "AbstractAction".  
    AbstractAction appears in right pane, and
    "AbstractAction" appears in tab title and frame title.
 b. in lower left pane, click 2nd link: "AbstractBorder".
    AbstractBorder appears in right pane, and
    "AbstractBorder" appears in tab title and frame title.
 c. in lower left pane, click 3nd link: "AbstractButton".
    AbstractButton appears in right pane
    "AbstractButton" appears in tab title and frame title.
4. click the downward triangle (v) under the back (<) button.

[Radha on family leave (not reading bugmail)]

This site specifically sets the title for the parent document (thro' onLoad
handler) everytime a page is loaded in any subframe. This looks good and fine
when you are looking at the title bar and the tab title. But this confuses some
of the data structures that docshell and session history maintain and  therefore
shows wrong titles in the go/back and forward menus. I don't this problem in
other frameset pages. Marking "won't Fix".

Radha's helpful diagnosis narrows down the problem and shows it may not be as
general as implied by the title, but I still think there is a bug here to be fixed.

1. The history session should not become 'confused' as Radha put it.
2. There is no more 'correct' way of making title of the main pane visible in
titlebars and history (other panes are for navigation, and a static frameset
title is not helpful in the back/forward history).
3. Internet Explorer (6) displays the history titles correctly in its back and
forward button drop downs.
4. javadocs are a highly visible frameset, used by thousands of Java programmers
many times a day, not only for the standard java apis but also for as the
generated documentation for libraries.   These developers may try
Mozilla/Netscape, but this problem may contribute to perceiving Mozilla/Netscape
as still somewhat broken compared to IE, and thus they may be less likely to
support it.

So I think there is still a bug to be fixed, though it may be low priority. 
Perhaps leave the bug open and change the milestone to 'future' rather than
closing it as 'wont fix'?   Or should I submit a new bug report?
