Yes and no. If I add the World_Topo_Map as a ArcGISTiledMapServiceLayer I get the same errors. If I add it as a ArcGISDynamicMapServiceLayer, I don't get the errors. I don't think that's a good solution because I don't want to render it dynamically.
I don't know how to set the basemap other than using map name. By the way, I also tried other basemaps, street, oceans etc. All of them result in the same error. For example:
ahh ok so it is only on the layer you set as a basemap when you define your map object?
did you post your code where you do new Map
That's right it happens for the baseMap. My original code for the map was posted earlier but here it is again:
var effortMap = new Map("effortMap", {
center: [-122.3348, 47.5978],
zoom: 6,
sliderStyle: "large",
basemap: "streets"
});
I only did the basemap as a layer per your request to see if the link you sent me worked.
