16377 - form data not preserved on forward

Status: VERIFIED FIXED

(Core :: Layout: Form Controls, defect, P3)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

DESCRIPTION:  Form data is preserved if you click a link on the page with the
form and then hit "Back".  However, it isn't preserved if you hit "Forward" on
the page with the form and then hit back.

STEPS TO REPRODUCE:
 1) Load http://bugzilla.mozilla.org/query.cgi
 2) Put a name in the email field
 3) click on the "mozilla.org" link near the top
 4) click "Back".  The name's still there.
[repeat (3) and (4) if desired]
 5) click "Forward"
 6) click "Back"

ACTUAL RESULTS:  The name is gone.

EXPECTED RESULTS:  It should still be there.

DOES NOT WORK CORRECTLY ON:
 * Linux, apprunner, 1999-10-13-12-M11

I'll save Chris some time on this one.  I think this should go to Eric or Radha
because they worked on implementing the session history stuff.  Re-assigning
this to Eric first and ccing Radha.

Also does not work correctly on: 1999-10-12-16-M11 mozilla.exe on Windows NT

Radha, I'm betting this is yours.
When I reproduced this on yahoo.com, I got this printf:

nsLayoutHistoryState::GetState, ERROR getting History state for the key

Looking in nsLayoutHistoryState::GetState, this should only happen if the state
you fetch is null.  My guess is that it was released already?
