Mapviewer view zoomed out within BI report

Question

Hello,
I'm trying to troubleshoot an issue with a mapviewer map within a BI report showing the map zoomed way out. This map is a FL state map with the cities within the states marked. The geometry theme "FL_CITIES" preview fine on the MapBuilder.jar client application.
However, when rendering the map in OBI report, Mapview just shows a grey screen. When I click on the map, then a small map of FL displays, but it is zoomed out.
I tried to update the mapZoom to a different number on
mapview.setZoomLevel(mapZoom);
but there is no change in rendering of the map.
Has anyone else encountered this behavior? I'm on 10.1.3.3. I've cut and pasted the showMap() function:
function showMap()
baseURL = "http://"+document.location.host+"/mapviewer";
var mpoint = MVSdoGeometry.createPoint(-82.6, 28.2,8307);
mapview = new MVMapView(document.getElementById("map"), baseURL);
var mapZoom = 0;
mapview.addBaseMapLayer(new MVBaseMap("MVDEMO.DEMO_MAP"));
mapview.setZoomLevel(mapZoom);
mapview.addCopyRightNote(
"<font color=black>"+
"Oracle MapViewer"+
"</font>"+
"&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp");
mapview.addMapTileLayer(new MVBaseMap("elocation_mercator.world_map","http://elocation.oracle.com/mapviewer/mcserver" ));
var mapZoom=5;
mapview.addCopyRightNote("Oracle eLocation - &#169;2008 Oracle Corp. &#169;2008NAVTEQ&#8482;");
mapview.addNavigationPanel("WEST",false,false,null);
mapview.setCenter(mpoint);
mapview.setZoomLevel(mapZoom);
flFOI = new MVThemeBasedFOI('flFOI','mvdemo.fl');
mapview.addThemeBasedFOI(flFOI);
countiesFOI = new MVThemeBasedFOI('countiesFOI','mvdemo.fl_counties');
mapview.addThemeBasedFOI(countiesFOI);
regionsFOI = new MVThemeBasedFOI('regionsFOI','mvdemo.fl_cities');
regionsFOI.setRenderingStyle("V.UI_DATA_CITIES");
//setupNsdp(regionsFOI);
regionsFOI.setBoundingTheme(true);
// regionsFOI.enableLabels(true);
mapview.addThemeBasedFOI(regionsFOI);
mapview.display();
