GeoServer WFS OpenLayers EditingPanel Problem

Question

I'm trying to use OpenLayers to edit features of vector data served from a local geoserver. So far, I'm able to pull WMS and WFS layers using OpenLayers from the same geoserver. But now, I'd like enable editing of features of the vector layers. The relevant code section is as shown below:

var ke_admin_vector = new OpenLayers.Layer.Vector("Admin Vector", {
           strategies: [new OpenLayers.Strategy.BBOX(), new OpenLayers.Strategy.Save()],
           protocol: new OpenLayers.Protocol.WFS({
               version: "1.1.0",
               url: "http://HOST_IP:port/geoserver/wfs",
               featureType: "ke_admin",
               featureNS: "pop_explorer",
               srsName: "EPSG:4326"
           })
       });

       var editpanel = new EditingPanel(ke_admin_vector)
       map.addControl(editpanel);

ke_admin is the name of the layer. pop_explorer is the workspace url. EPSG:4326 is the projection of the layer within geoserver.

When I try accessing this from a browser, firebug complains that EditingPanel is not defined. Any suggestions on what I may be doing wrong. Thanks in advance.

I was following the tutorial at workshops.opengeo.org/openlayers-intro/vector/persist.html. As it turns out, the EditingPanel.js, DeleteFeature.js and editing-panel.css referenced in the tutorial are available at http://svn.opengeo.org/workshops/projects/openlayers/foss4g_2009/src/extras/. The workshop assumed the learner had downloaded everything.
