JavaScript Popup Window

Question

Hi, has anyone done an example where you are at a page, say Page1.jsp that has a text box and a button, when you click on the button a javascript popup window must open(Page2.jsp). Page2.jsp has a text box and a button. The user will enter a value in the text box and when they click the button it must close the popup window and populate the text box on Page1.jsp with the value entered on Page2.jsp.
Is this possible in JSF, I have tried but it doesn't work. On the popup windoow botton I have javascript code that saves the value in the session, submits the parent page and then closes the popup window.
On the parent page init, I look for the value saved in the session var and set the textbox's text to it. When I read the value of the text box, it is right but on the screen the value does not show up at all,
Does anyone have any idea, I can't seem to understand at all what could be wrong here.

Hi,
You can use this code:
1. in the parent form you have a button and a text field named "textCallClass".
2. in the popup window you have listbox and a button.
When the button on the popup window is clicked, the selected list item is returned.
In you popup window, button on_click :
                    <script>
                        function handleOK() {
                            var myform      = document.forms[0];
                            var listControl = myform['form1:listboxID'];
                            var openerField = window.opener.document.getElementById("form1:textCallClass");
                            if (listControl.selectedIndex == -1) {
                                alert ("Please select an item from the list !");
                                return false;
                            else {
                                openerField.value = listControl.options[listControl.selectedIndex].value;
                                window.close();
                    </script>In the parent form, button on_click:
                        function handleCallClassPopup() {
                            window.open("CallClassLookup.jsp", "Lookup", "width=250,height=300");
                        }A better way is to use the SessionBean to store and retrieve the data.
