I added them back in this way: var basemaps = [];
var BingBaseMapRoad = new esri.dijit.Basemap({
layers: [new esri.dijit.BasemapLayer({
type: "BingMapsRoad"
})],
id: "bmRoad",
title: "Bing Roads",
thumbnailUrl: "images/BingMapsRoad.png"
});
basemaps.push(BingBaseMapRoad);
var BingBaseMapAerial = new esri.dijit.Basemap({
layers: [new esri.dijit.BasemapLayer({
type: "BingMapsAerial"
})],
id: "bmAerial",
title: "Bing Aerial",
thumbnailUrl: "images/BingMapsAerial.png"
});
basemaps.push(BingBaseMapAerial);
var BingBaseMapHybrid = new esri.dijit.Basemap({
layers: [new esri.dijit.BasemapLayer({
type: "BingMapsHybrid"
})],
id: "bmHybrid",
title: "Bing Hybrid",
thumbnailUrl: "images/BingMapsHybrid.png"
});
basemaps.push(BingBaseMapHybrid);
