Our customer wants to use their own basemap, which has different wkid with esri's default wkid.
To createmap, API allows to pass following valid options: "streets" , "satellite" , "hybrid", "topo", "gray", "oceans", "national-geographic", "osm" to the parameter "basemap", according to API reference.
What I am doing is, temperately use "topo" as basemap when creating map, then use BasemapGallery.select(id) to switch to customer's basemap. However, since customer's basemap and esri's topo basemap wkid are different, I am hitting error Map: Geometry (wkid: 102100) cannot be converted to spatial reference of the map (wkid: 3417) .
Is there a anyway to workaround?
Thanks for your help!
