I am having the weirdest problem right now using the ArcGIS Javascript API (v2.4). I'm merely trying to create an instance of an ESRI topo map with an extent, and then add a layer.
Here is the code that works. I create an extent, then a map, then a streetmap layer and then finally add that layer.
var startExtent = new esri.geometry.Extent(-71.5, 42, -71, 42.5, new esri.SpatialReference({wkid:4326}) ); map = new esri.Map("map_canvas", { extent: startExtent,fitExtent:false }); var streetmap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer"); map.addLayer(streetmap);
However when I try and do the same thing with a separate server, it doesn't work.
var startExtent = new esri.geometry.Extent(-71.5, 42, -71, 42.5, new esri.SpatialReference({wkid:4326}) ); map = new esri.Map("map_canvas", { extent: startExtent,fitExtent:false }); var basemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"); map.addLayer(basemap);
I know that the faulty-layer's server works, because if I create a map with no extent, it shows the full world imagery server, so it appears that creating a map in with one layer and an extent works, while creating a map with a different layer but the same extent does not work.
Any ideas why?
