Matt,
Based on your onsubmit suggestion, I changed my
code to submit the form from:
document.forms['body:theForm'].submit();
to
if(document.forms['body:theForm'].onsubmit)
{
if(document.forms['body:theForm'].onsubmit())
document.forms['body:theForm'].submit();
}
else
{
document.forms['body:theForm'].submit();
}
Now it works! the parent page refreshes with the
populated value retained.
One strange thing though, I don't see
JSF rendering a onsubmit() function inside the form tag. Anyway, it's
working.
thanks a lot for the help, Matt &
whoever responed to the question
Saul.

Subject: Re: Using _javascript_ to submit a
form doesn't work
You can see for yourself what the _javascript_ code that's being
generated is, just by running the page and using your browser's View Source
functionality.
If there's an onsubmit handler, the code you list will
do exactly what needs to be done. It's possible, though, that there's an
onchange handler on the input box (say, that populates a hidden field) that
may not be called when the value changes
programmatically.

Yes,
I do have two commandButton there in the parent window. I just
populate
one id value to the parent window and I see it showing up in the
input
box before the parent window refreshes. Once the parent window
refreshes
though, it clears out the value populated in the input box. I'm
sure JSF
generate a bunch of _javascript_ code, may be I need to call the
onsubmit
before calling submit, something like
this:
parentWinForm.onsubmit();
parentWinForm.submit();
thanks.
