I am unclear on exactly how to create a hybrid basemap in AGOL. I checked out the local government sample which appears to implement the map as an aerial basemap with an operational road overlay. http://www.arcgis.com/home/item.html?id=9c8b3044c4054d59b658184c3737c432I've also created a group that has all my basemaps. This works great in the Javascript API basic viewer template when I supply the group id to the basemapGallery.Except the hybrid map I created in AGOL does not display the roads overlay. It does display the overlay when you view it in the ArcGIS.com map viewer.I am able to successfully create the hybrid manually using code as follows: basemapGallery.add(new esri.dijit.Basemap({
layers: [
new esri.dijit.BasemapLayer({
"url": "http://myserver/ArcGIS/rest/services/Roads/MapServer"
}),
new esri.dijit.BasemapLayer({
"url": "http://myserver/ArcGIS/rest/services/AerialPhoto/2012/MapServer"
})
],
title: "2012 Hybrid Aerial Photo",
thumbnailUrl: "http://myserver/mythumb.jpg"
}));I inspected the JSON coming out of AGOL and I think the problem is that the overlay is being marked as an operational layer rather than a second base layer.Is there anyway to add more than one base layer to an AGOL map?Is there a different way that I am supposed to implement the hybrid basemap?I'd rather not burn the roads overlay into a second cached map service separate from the aerial photo cached map service.Thanks for any suggestions!
