Is is possible, in the ArcGIS Javascrpit API, to get an ArcGisDynamicMapServiceLayer to render in a different colour, or would the ArcGIS Service need to be changed? Thanks! ... View more

Hey all, I have a quick question regarding the ArcGIS Rest end points.... What is the "Maximum Allowable Offset" parameter? I know it generalizes on the fly (fantastic) but what are the units? Is it in meters? radians? rubber chickens? Thanks! ... View more

Hello, I would like to know if there is a REST service (and perhaps a JSAPI function) that can get the extent of a set of polygons without having to return the geometry to the browser. So it would work like this: 1) Make a rest query to ArcGIS server with a where clause like "STATE_CODE in ('TX','CA','NY')" 2) Return a JSON esri.geometry.Extent object. Does this function, or something similar exist? ... View more

Hi, I've noticed that in the examples on the ESRI website that the X-UA-Compatible content="IE=7" meta html tag is still required for the maps to display correctly in IE9... this tag can introduce errors in other libraries, like JQuery (which is what i am seeing in my application). So my questions are 1) Is there any other way to "tell" the arcgis javascript api to fall back to IE-7 compatibility mode, without having to specify the meta tag? 2) Why is this meta tag still required? Regards ... View more

Hello, I am currently testing the ArcGIS Server Export Map functionality on the ESRI ArcGIS 10 sample servers and it appears as though the service does not operate as I expected. Basically I am attempting to export one feature (STATE_FIPS='20') on one layer (layer Id 5), along with all the features on another layer (layer id 2) to png format. I am able to show both of the layers, however the layer definition I attempt to apply to layer Id 5 seems to go unnoticed by the server �?? all features are returned for *both* layers instead of just the single state with id 20. Clicking on the following link will show the parameters that I am using to make the request: http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/export?bbox=-185.337909350544,-19.11255617006,-59.5254875059344,108.400033537315&bboxSR=4269&layers=show:5,2&layerdefs=STATE_FIPS%3D'20'&size=&imageSR=4269&format=png&transparent=false&dpi=&f=html Any help appreciated Thanks ...

Hi I am getting a JavaScript exception when selecting features from a FeatureLayer on the map. The selection *seems* to work (i.e the features are highlighted), however firebug reports this error: dojo.io.script error Error: Deferred Cancelled cancelResult: undefined dojoType: "cancel" fileName: http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0 lineNumber: 16 message: "Unable to draw graphic (null): Deferred Cancelled" name: "Error" stack: "Error("Deferred Cancelled")@:0 ()@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 ([object Object],0,[object Array])@http://serverapi.arcgisonline.com/jsapi/arcgis/2.0/js/esri/layers/FeatureLayer.xd.js:19 ([object Array],(function (dfd, id) {dfd = dfd || _4.io.script["jsonp_" + "dojoIoScript" + id];if (dfd) {try {dfd.cancel();_4.io.script._validCheck(dfd);} catch (e) {}}}))@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 (true)@http://serverapi.arcgisonline.com/jsapi/arcgis/2.0/js/esri/layers/FeatureLayer.xd.js:19 ([object Object],4,[object Object],6)@http://serverapi.arcgisonline.com/jsapi/arcgis/2.0/js/esri/layers/FeatureLayer.xd.js:19 ([object Object],4,[object Object],6)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 ([object Object],4,[object Object],6)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 ([object Object],4,[object Object],[object Object],true)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:52 ([object HTMLDivElement])@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:52 ([object HTMLDivElement])@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 ("onEnd",[object Array])@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 (148)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 (148)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 (148)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 (148)@http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0:16 " Firebug also reports the following error: dojo.io.script.jsonp_dojoIoScript_postcodes00_0_02197265625_1_3 is undefined Here is the code I am using: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head>   <meta http-equiv="Content-Type" content="text/html;
