The same strategy applies. After you grab the URL using esri.urlToObject(), create a dynamic map service layer and add it to the map.

Yes, the "Border and Margin" ArcGIS.com sample show this. Here's the URL for the sample: http://help.arcgis.com/en/webapi/javascript/arcgis/demos/ags/ags_fullmaplayoutwithborderandmargin.html And here it is with a URL parameter for a webmap: http://help.arcgis.com/en/webapi/javascript/arcgis/demos/ags/ags_fullmaplayoutwithborderandmargin.html?webmap=d902ef17333c4dbe9e0caa05e067ec89

Don't let the well-known text in the initial extent's spatial reference throw you off, it works the same if you use a WKID.

The geographicToWebMercator helper method only converts lat, long coordinates to web mercator while the geometry service's project method does not have this restriction. The geometry service supports re-projecting from any of the coordinate systems listed in the help: http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/pcs.html http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/gcs.html Also, geographicToWebMercator works on a single geometry while the geometry service can works with one or more geometries. The only downside of the geometry service is that it requires a server round trip while geographicToWebMercator is all client side.

Hi Steve, Identify always returns all attributes...see: http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/identify.html You could not expose certain fields in your map service but that's probably not ideal. For the aliases, take a look at this post: http://forums.arcgis.com/threads/7793-Identify-How-to-show-Alias-filed-instead-of-Field-Name?p=24158&viewfull=1#post24158

They do two different things. getLength calculates a Eudclidean distance AKA planar distance which assumes the world is flat. This is appropriate for short distances and/or when you're using a projected coordinate system, e.g. a UTM zone or State Plane. geodesicLengths calculates a geodesic distance which is a measurement on a sphere. This is appropriate when you're measuring long distances on a globe. I'll also throw in a plug for a blog post Sterling from the server team did a while back about using the right coordinate system when measuring distances in a web app: Measuring distances and areas when your map uses the Mercator projection.

Can you follow the pattern in the Feature Layer On Demand sample where you load your feature layers after the map loads? Relevant code:
function init() {
map = new esri.Map("map", { extent: esri.geometry.geographicToWebMercator(extent)});
dojo.connect(map, "onLoad", initOperationalLayer);
}
function initOperationalLayer(map) {
var content = "<b>Type</b>: ${ftype}" +
"<br /><b>Code</b>: ${fcode}";
var infoTemplate = new esri.InfoTemplate("Rivers", content);
var featureLayer = new esri.layers.FeatureLayer("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Hydrography/Watershed173811/FeatureServer/1",{
mode: esri.layers.FeatureLayer.MODE_ONDEMAND,
outFields: ["*"],
infoTemplate: infoTemplate
});
map.addLayer(featureLayer);
} Also, it looks like the map.setExtent function call in your init function is unnecessary.

Technically, it's wouldn't be an error in Firebug, just a warning. What do you see in the console? Are there any messages? Can you modify your view to include your layer's objectID?

I think we should clarify some terms... When I said popup, I was referring to the popup widget that was introduced with version 2.3 of the API. I'm not sure what you mean by dojo popup but let's ignore that for now. If you define an infoTemplate when you create your feature layer, you should see an info window when you click your features. See the ON_DEMAND feature layer sample for an example.
