Refreshing predefined FOI in 11g

Question

I am working on Mapviewer 11g on Jdeveloper 11g using ADF. I managed to display the base map and predefined theme FOI. I am now trying to just refresh the theme based FOI (predefinedTheme1) on user clicking the 'Refresh Now' command button, How do I do it?. I am attaching the JSPX file with the code.
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:h="http://java.sun.com/jsf/html"

xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
xmlns:dvt="http://xmlns.oracle.com/dss/adf/faces">
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<f:view>
<af:document>
<script type="text/javascript">
<![CDATA[
var mapview;
baseURL = "http://"+document.location.host+"/mapviewer";
mapview = new MVMapView(document.getElementById("map"), baseURL);
alert(baseURL);
function refreshFoi()
var themebasedfoi1 = mapview.getThemeBasedFOI('themebasedfoi1');
var themebasedfoi2 = mapview.getThemeBasedFOI('themebasedfoi2');
var themebasedfoi3 = mapview.getThemeBasedFOI('themebasedfoi3');
var themebasedfoi4 = mapview.getThemeBasedFOI('themebasedfoi4');
themebasedfoi1.refresh();
themebasedfoi2.refresh();
themebasedfoi3.refresh();
themebasedfoi4.refresh();
function autoRefresh()
if ((document.getElementById('foiVisible').checked) && (document.getElementById('refreshAuto').checked))
refreshFoi();

Hello!
And why you create new MVMapView ?
(mapview = new MVMapView(document.getElementById("map"), baseURL);)
If you use dvt:map the variable "map" alredy is in javascript page scope.
This is AdfDhtmlGeoMap object.
This code find the current map instance:
if (map) {
var mapview = map.getMVMapView();
You may use Firebug in FF to check this.
If you use dvt:map jsp page contains _AdfDhtmlGeoMap-SHEPHERD-PS1-9296.js.
It includes AdfDhtmlGeoMap prototype and other mapviewer object such MVMapView, MVSdoGeometry, MVMenu etc.
