I'm not understanding this, but it doesn't sound like form manager.  Reassigning.

in the future, please use the bugzilla helper:
http://bugzilla.mozilla.org/enter_bug.cgi?format=guided

this actually looks like Form Submission or DOM.  when you hit "More Phrases" it
should load a new page that has an additional set of form elements (a fourth one).
Steps to reproduce:
1. open http://search.lycos.com/adv.asp  (page has three text boxes)
2. hit "more phrases" button

The page should load with 4 text boxes, but only has 3.

This works in NS4, but not Mozilla (with linux 1.0 release or trunk build
20020921).  Taking the URL (it is submitted via GET) from NS4 and using that in
Mozilla, it pulls up the correct page (it has 4 text boxes)

marking NEW and reassigning.  will probably reassign again once I figure out
what's going on.

when you hit the "More phrases" button (which is actually an <input name="nwfc"
type="image">, it calls a function that changes the form's action from
"default.asp" to "adv.asp", and then submits it.  If I reset the initial action
to "adv.asp" and change the button's onclick handler to do "this.submit()", it
works properly.

the difference in submitted URLs is that the nwfc's fields are not submitted in
the original.  here are the two URLs:

http://search.lycos.com/adv.asp?loc=searchbox&tab=&query=&adv=1&wfr=&wfw=&wfq=&wfr=%2B&wfw=&wfq=&wfr=-&wfw=&wfq=&wfc=3&df0=i&dfq=&df1=e&dfq=&dfc=2
http://search.lycos.com/adv.asp?loc=searchbox&tab=&query=&adv=1&wfr=&wfw=&wfq=&wfr=%2B&wfw=&wfq=&wfr=-&wfw=&wfq=&wfc=3&nwfc.x=22&nwfc.y=6&df0=i&dfq=&df1=e&dfq=&dfc=2
the first one lacks nwfc fields and does not work

==> Form Submission (?)

Attachment: testcase

testcase.  the first does "document.forms[0].submit()" and the second just does
"this.submit()".  The first one doesn't work about half the time.

Comment 5

[Vladimir Ermakov]

Dupe of "Submit name/value pairs for submit buttons that triggered javascript
submission"

The issue is that when mozilla submits from javascript as a result of clicking
on an image it does not submit x/y coordinates, but IE and Netscape 4.x do.
