In chapter 4 page 84 - 85 you demonstrate how to add a map using the gray esri basemap layer. Can I do the same thing using an ArcGIStiledMapServerLayer?.. how?
Thank you for a great book!

Well, to answer my own question I did this...

In mapcontroller.js after the line: this.map = new Map(this.options.elem, this.options.mapOptions);

I added the following code:

var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://myserver/ArcGIS/rest/services/Basemaps/Basemap_aRoads/MapServer");

this.map.addLayer(basemap);

I also added "esri/layers/ArcGISTiledMapServiceLayer" under define.

Then in main.js I commented out //basemap: 'topo'

... voilà it worked!

I'm glad you found a solution! If you need anything else, just let me know. Thanks!

I was also able to replace the ArcGIStiledMapServerLayer with a ESRI BasemapToggle widget and it works well too. I'm pretty excited about the possibilities!
