Oracle maps : setHomeMap

Question

Hi,
I am trying to use the
setHomeMap(mpoint, nZoom) function:
" .. When the home map location and zoom level is set, the user can click on the center button of the navigation panel to bring the map back .."
but the center button of the navigation panel does not exist in my navigation panel .
Many thanks,
Friedhold

Sure:
function loadMapView() {
//The MapView URL...
var URL="http://xxxx/mapviewer";
//Create a new MVMapView Object, using the 'map-handle' <div> and the MapViewer URL...
mapview=new MVMapView(document.getElementById("map-handle"), URL);
//Custom 'addBaseMaps function...
addBaseMaps();
//Set the MapView Center and ZoomLevel, using the default x, y, and z parameters...
//Create a 'center', using the 'MVSDOGeometry.createPoint' function, the default x and y parameters, and the BNG36 SRID (81989)...
var center=new MVSdoGeometry.createPoint(parseFloat(x), parseFloat(y), 81989);
//Create a 'zoomLevel' using the default z parameter...
var zoomLevel=parseInt(z, 10);
//For some reason, the combined 'setCenterAndZoomLevel' function doesn't work if the ZoomLevel is 0...
mapview.setCenterAndZoomLevel(center, zoomLevel);
//Display the MapView, using the 'display' function...
mapview.display();
Something to do with the different SRID's maybe?
