I would recommend replacing the pop up window with an in-page modal
window (http://ui.jquery.com/repository/latest/demos/functional/
#ui.dialog). The modal windows these days are advanced enough to
function much like a pop up window with draggable, resizable, scolling
and whatnot. This would be easy to do if you were to use a modal
window because once hidden form field is populated you can us jQuery's
event trigger method (http://docs.jquery.com/Events/trigger#typedata)
to make it happen.
If you absolutely need to use the pop up window then have the new
window call a function in the parent window. This function can execute
a trigger.
//this function is in the parent window.
function triggerHiddenFormField() {
$('$hiddenFormField').trigger('change');
}
//pop up window calls the the parent window's function
window.opener.triggerHiddenFormField();
