Can't get basemap using js 3.10+ and proxy rules

Question

Hi,

If I use the 3.9 of the ArcGIS Javascript library this works fine, but I've found if I use 3.10 or 3.11 I no longer get basemaps.

I'm adding the proxy rule like this:

esri.urlUtils.addProxyRule({

urlPrefix: "server.domain.com",

proxyUrl: "http://localhost/proxy/proxy.ashx"

});

I'm adding my map like this:

map = new esri.Map("mapDiv", {

center: [-100.167, 48.167],

zoom: 5,

basemap: "topo"

});

If I remove the proxy rule the basemap comes up fine.  The proxy I'm using is the one from github

Any suggestions?

I finally solved this by waiting until the secured layers were getting loaded.  I put a load listener on a featureLayer to create the basemapGallery then.  No more errors and switching basemaps works as well.

on(app.secureLayer, 'load', function (evt){

var basemapGallery = new BasemapGallery({

showArcGISBasemaps: true,

map: app.map

}, "basemapGalleryDiv");

basemapGallery.startup();

on(basemapGallery, "error", function(msg){

console.log("basemap gallery error:  ", msg.message);

});

The initial error seems to come from this ServerInfo definition:

var serverInfo = new ServerInfo();

serverInfo.server = pathName;

serverInfo.tokenServiceUrl = pathName+"/arcgis/tokens/generateToken";

I'm not sure why I had that in the first place.   I commented these lines out and there is no error when I load the map.  I'm still getting the error when I try to switch basemaps, though.

I'm having a very similar problem.  I added a proxyRule for my local secure server, but do I need to add another one for the ESRI base maps?  I am getting an initial basemap from my map creation.  I'm getting errors when creating a BasemapGallery.

The error comes when I first load the page:

esri.dijit.BasemapGallery:  Unable to find the 'map' property in parameters.

I use BasemapGallery in nearly all my maps and I know the syntax is pretty straight forward.  I have loaded the Search widget using the exact same syntax for the map parameter and it loads just fine.

//basemapgallery widget

app.basemapGallery = new BasemapGallery({

showArcGISBasemaps: true,

map: app.map

}, "basemapGalleryDiv");

app.basemapGallery.startup();

app.basemapGallery.on("error", function(msg){

console.log("basemap gallery error:  ", msg.message);

});

Even with the error, the thumbnails load OK  in my side panel, but when I try to change the basemap I'm getting the error

basemap gallery error:   esri.dijit.BasemapGallery: could not find group for basemaps.

The only difference between this map and others is that I have secured services, so I need the proxy set up and I'm using IdentityManager.
