Adding multiple FOI themes with MapViewer with jdbc_query

Question

Hi,
I'd like to add two themes to a map with the Javascript Mapviewer.
When I use mapview.addThemeBasedFOI(theme); only the theme that finished loading first will display. Is it possible to add multiple themes or am I doing something wrong?
The second thing I tried was using a jdbc_query theme. My javascript looks like this:
           var baseURL = "http://" + document.location.host + "/mapviewer";
            // Create an MVMapView instance to display the map
            var mapview = new MVMapView(document.getElementById("map"), baseURL);
            // Add a base map layer as background.
            mapview.addBaseMapLayer(new MVBaseMap("mvdemo.demo_map"));
            // Add a theme-based FOI layer
            var theme = '<themes><theme name="JDBC_THEME2" >' +
                        '<jdbc_query asis="true" spatial_column="location" jdbc_srid="8307" ' +
                        'render_style="C.RB13_6" datasource="mvdemo">' +
                        '<![CDATA[select sdo_geom.sdo_buffer(A.location,1,0.005,' +
                        '\'unit=mile arc_tolerance=0.005\') location ' +
                        ' from customers A where sales<=100]]>' +
                        '</jdbc_query></theme><theme name="JDBC_THEME" >' +
                        '<jdbc_query asis="true" spatial_column="location" jdbc_srid="8307" ' +
                        'render_style="C.RED" datasource="mvdemo">' +
                        'select sdo_geom.sdo_buffer(A.location,1,0.005,' +
                        '\'unit=mile arc_tolerance=0.005\') location ' +
                        ' from customers A where sales>100' +
                        '</jdbc_query></theme></themes>' ;
            console.log(theme);
            buffertheme = new MVThemeBasedFOI('buffertheme', theme);
            mapview.addThemeBasedFOI(buffertheme);
            // Set the initial map center and zoom level
            mapview.setCenter(MVSdoGeometry.createPoint(-122.45, 37.7706, 8307));
            mapview.setZoomLevel(4);
            // Add a navigation panel on the right side of the map
            mapview.addNavigationPanel('east');
            // Add a scale bar
            mapview.addScaleBar();
            // Display the map.
            mapview.display();I used the examples from page 222 and 225 from the Mapviewer manual (mapviewer_10131_ug.pdf) and it uses the MVDEMO schema.
The xml for the themes:
<themes>
    <theme name="JDBC_THEME2">
        <jdbc_query asis="true" spatial_column="location" jdbc_srid="8307" render_style="C.RB13_6" datasource="mvdemo">
            <![CDATA[select sdo_geom.sdo_buffer(A.location,1,0.005,'unit=mile arc_tolerance=0.005') location from customers A where sales<=100]]></jdbc_query>
    </theme>
    <theme name="JDBC_THEME">
        <jdbc_query asis="true" spatial_column="location" jdbc_srid="8307" render_style="C.RED" datasource="mvdemo">
            select sdo_geom.sdo_buffer(A.location,1,0.005,'unit=mile arc_tolerance=0.005') location from customers A
            where sales>100
        </jdbc_query>
    </theme>
</themes>In this example I want to display 2 different colors, one for sales>100 and one for sales<=100. Again, only the first color is displaying. I searched for some examples and found <map_request> xml files where multiple themes are allowed, is it also allowed with the Javascript Mapviewer?
Thanks for you help!

Hi
Are you trying to concatenating or adding it ? i mean you said adding year measure1measure2
year is character type so i guess that you want to display like 2011 45000 isnt it
then use concatenation or try to change the measure value to dimension to keep side by side
Hope this helps u
