John, Please try the case with xmax greater than 180. var bbox = new esri.geometry.Extent({"xmin": 175.0, "ymin": 15.0, "xmax": 185.0, "ymax": 25.0, "spatialReference": {"wkid": 4326}}); Thanks.

Tomek, Snapping will work with any coordinate systems in 2.4 release. Currently, it only works with GCS and Web Mercator. Thanks.

Please try this:
var measurement = new esri.dijit.Measurement({
map: map
}, dojo.byId('measurement'));
measurement.startup();
var area = dojo.query('[widgetid=\"area\"]')[0];
area.parentNode.removeChild(area);

SnappingManager works with any coordinate systems. Please try the code below. Hope this helps.
<script type="text/javascript">
dojo.require("esri.map");
dojo.require("esri.layers.FeatureLayer");
dojo.require("esri.SnappingManager");
dojo.require("esri.toolbars.draw");
var map, snap, featureLayer;
function init() {
var extent = new esri.geometry.Extent({"xmin":-96.6063,"ymin":38.3106,"xmax":-96.4764,
"ymax":38.3689,"spatialReference":{"wkid":4269}});
map = new esri.Map("map", { extent: esri.geometry.geographicToWebMercator(extent)});
var imagery = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer");
map.addLayer(imagery);
featureLayer = new esri.layers.FeatureLayer("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Hydrography/Watershed173811/FeatureServer/1",{
mode: esri.layers.FeatureLayer.MODE_ONDEMAND
});
map.addLayer(featureLayer);
dojo.connect(map, "onLoad", initSnapping);
}
function initSnapping(themap) {
var map = themap;
snap = new esri.SnappingManager({layerInfos:[{layer:featureLayer, snapToPoint: true, snapToEdge:false}], map: map, tolerence: 500});
toolbar = new esri.toolbars.Draw(map);
dojo.connect(toolbar, "onDrawEnd", addToMap);
}
function addToMap(geometry) {
toolbar.deactivate();
map.showZoomSlider();
var sPt = map.toScreen(geometry);
var defer = snap.getSnappingPoint(sPt);
defer.addCallback(function(result){
if(result){
var snapPoint = result;
console.log(snapPoint);
}
});
var symbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 10, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 1), new dojo.Color([0, 255, 0, 0.25]));
var graphic = new esri.Graphic(geometry, symbol);
map.graphics.add(graphic);
}
dojo.addOnLoad(init);
</script>

Phillip, This is a known limit of the algorithm itself, instead of a bug. When two points are nearly antipodal to each other, the algorithm couldn't converge to get the geodetic distance and azimuth. We will "fix" the issue by implementing another algorithm when the case happens. Thanks.

Sam, The method getSnappingPoint() accepts screen point, instead of map point. Please call map.toScreen before passing it to the method. Thanks.

Please take a look at the document of SnappingManager. The method getSnappingPoint() returns a deferred object, which contains the closest point from a input location. Hope this helps.

Gabi, After looking at your app, I realized that it points to a 9.3.1 geometry service, which results in a different value when calculating area. Please use a version 10 server geometry service. Well thank you - thank you that certainly helped!... Thank you

wkid should be global variable. Please put the line of code outside any functions. We are going to patch the bug. Sorry about any inconvenience.

Only the newest version of Opera shows the issue. It seems that Opera doesn't like the ticks. If setting tick as 0 in esri.config.defaults.map.sliderLabel, it works fine. Of course, that would lose the ticks. Please add the following code to the init() function: if (dojo.isOpera) { esri.config.defaults.map.sliderLabel = {labels:null,style:"width:2em; font-family:Verdana; font-size:75%;",tick:0}; } Hope this helps.

Please refer to the doc at: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/scalebar.htm It documents as: <String> scalebarUnit Specify the scalebar units. Valid values are "english" or "metric". The default value is "english". Thanks.

Unfortunately, there is no public available plan for the future. For snapping, yes, it's under consideration at the version 2.3. If you have any specific request for more functionalities, please let me know. Thanks for your feedback.

JavaScript 2.2 (next release) will have a method esri.geometry.geodesicAreas to calculate the geodesic areas of polygons. Hope this helps.

Thanks for the feedback, Todd. Is the issue browser specific? Could you please give me a step by step reproducible case? Thanks again.

Michael, Could you please provide more information? Did the service return back the geometry? You can debug it via firebugs. Please check the API doc at: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/geometryservice.htm#cut
