I just started using ArcGIS JS APIs. In my app, I want to combine a few ESRI basemaps with my own basemap service. I am using basemapGallery dijit to change basemaps. By default, basemapGallery shows the imagery map. I want to show OpenStreetMap as the default. How can I make this happen?
The code in my app is simple and directly borrowed from ArcGIS samples. So I did not put it here.
