David, I am not able to figure out the following:
Let us say I have a page A.jsp in which I have a hidden iframe called B.jsp. Now this page A.jsp has the select onchange call which in turn sets some values in the form present in the hidden iframe B.jsp and submits the form in the iframe B.jsp. Now on submit , is the action forward supposed to forward to A.jsp which has a javascript in it? I tried doing this but I am not able to populate the fields. Please let me know.
