Actually, I was incorrect... it's this bit of code that's preventing the KML from rendering: kml.on("load", function() {
domStyle.set("loading", "display", "none");
}); But, you can still set-up the basemap in the map constructor as an alternative way to show the topo layer. If you are curious, here's how it would look: map = new Map("map", {
basemap: "topo"
}); Many ways to skin a cat in the ArcGIS JSAPI! A Pen by Captain Anonymous - Forked

Jeremy, Try setting your basemap in the map's constructor. That's one way to solve it!

The legend will not render for me as a KML. I couldn't find a working sample, either - I even tried a few versions back in the API. Unless someone can find a working sample, I'm inclined to believe there may be a bug in the API as you've followed the instructions given by Esri, and the legend works when using the map service, but not the KML.

Kayla, I tried adding some map dbl-click events for the following sample: ArcGIS API for JavaScript Sandbox Using IE11, the double-click returns an object when double-clicking on the graphics. It works well when changing edit modes as well (right-clicking on the graphic will change the edit mode). Do you have a compatibility meta tag set anywhere? That has lead to problems for users, including myself, in the past.

Do you have any more details? Have you tried running a web debugger like Fiddler to see if there are any communication errors (Fiddler free web debugging proxy) or any errors in the browsers' dev tools/console (Chrome DevTools Overview - Google Chrome )?

Amanda, You could try the sinusoidal projection, aka the Sanson–Flamsteed or the Mercator equal-area projection. This would work well for Africa. Sinusoidal projection - Wikipedia, the free encyclopedia You may also find it helpful to learn more about coordinate systems, projections, and datums - these can be tricky to understand and are often dry topics, unless you find them interesting! But, it helps nevertheless to understand them: What are map projections?—Help | ArcGIS for Desktop http://web.gps.caltech.edu/gislab/HowTo/ESRI%20-%20Map%20Projections.pdf

Ok, I flipped some settings on the server - I can get my KML to render. I tried yours again and see it: I can get the legend to render with the map service: KML layers should be supported... I'm still not sure why it wouldn't show for the KML. I started debugging the legend.js API file and didn't hit key spots that would construct the legend, but there wasn't a clear, obvious reason why. Perhaps it's a bug in the API? Are there any examples showing this working? I couldn't find one...

I tried pulling the kmz for review - unfortunately, I was unable to display even the kml using the ArcGIS JSAPI - here's the kml layer: <?xml version="1.0" encoding="UTF-8"?>

Anand, Have a look at the following: Manage data store backups—Installation Guides (10.3 and 10.3.1) | ArcGIS for Server Here, you can find information on adjusting retention time, which can reduce disk space utilization: Change how long backup files are retained The backup directory retains backup files for 31 days by default. That means if you keep the default backup frequency (every 7 days) and retention schedules (31 days), the backup directory will contain five full backups and 31 days of incremental backup files. The size of these files depends on the amount and size of your data. The machine that stores your backups must have enough disk space for all these files. If you increase the backup frequency, consider decreasing the retention period for the backup files. In the previous section, the backup frequency was increased to every 14 days. To prevent your backup directory from becoming too large, decrease the backup file retention period. The syntax to run the updatebackupretaindays utility is as follows: updatebackupretaindays <number of days> In the following example, backup file retention time is changed to 27 days: updatebackupretaindays 27 On a side note for PostgreSQL installations, I've heard of some people using PostgreSQL: Documentation: 9.5: pg_archivecleanup for cleanup... I'm not sure if it's compatible with ArcGIS. Here's a discussion on better understanding what the tool will do: postgresql - I need help understanding Postgres's archive cleanup functionality - Database Administrators Stack Exchange

enableInfoWindow: true,
showInfoWindowOnSelect: false,

Ok, so it looks like hide will work, but you can't key off of the KML load event... it must be too early to call the hide method. It works if I use "update-end": kml.on("update-end", function() {
layers = kml.getLayers();
layers[1].hide();
console.log("layer hidden");
}); It doesn't seem to fire this more than twice. Panning and zooming doesn't cause the "update-end" to fire on a KML.

Charles, hide() does not work as anticipated, for some reason. Maybe it's a bug, maybe I'm not understanding it correctly. Using this sample - ArcGIS API for JavaScript Sandbox - I modified the kml to use the one you posted and here's what I found... var layers;
kml.on("load", function() {
domStyle.set("loading", "display", "none");
layers = kml.getLayers();
dojo.forEach(layers, function(layer){
layer.hide();
console.log(layer.visible);
});
}); In the console, both layers have visible as false, but they still show. As a workaround, try something like this (using opacity): <!DOCTYPE html>
