Hi, I'm trying to take the geometry of a geocoder search result and use that as the input geometry to query against a feature layer. If the geometry returned by the geocoder search result intersects a polygon in the feature layer, then a popup appears to display some of the attributes of the layer. This works fine for one-off address searches. It also works fine if I search for a new address after finding the first address and the new address is in a different polygon in the feature layer to the previous polygon that was selected in the first address search. However in the scenario where the first search is completed and a second address is searched and that second address intersects the same polygon as was selected by the first search, I'm having some problems. In this scenario the map first starts to recentre on the second address but then quickly zooms back to the location of the first address. In the console the following error messages appear: "exception in animation handler for: onAnimate TypeError: d is undefined .cache["esri/dijit/Popup"]/</e<._onPan()/3.8compact/ (line 543) .cache["dojo/_base/lang"]/</g.hitch/<()/3.8compact/ (line 173) .cache["dojo/aspect"]/</n/</h()/3.8compact/ (line 238) .cache["esri/_coremap"]/</p<._panningHandler()/3.8compact/ (line 828) .cache["dojo/_base/lang"]/</g.hitch/<()/3.8compact/ (line 173) .cache["dojo/aspect"]/</n/</h.around.advice()/3.8compact/ (line 238) .cache["dojo/aspect"]/</n/</h()/3.8compact/ (line 238) .cache["dojo/_base/fx"]/</<._fire()/3.8compact/ (line 44) .cache["dojo/_base/fx"]/</<._cycle()/3.8compact/ (line 48) .cache["dojo/_base/lang"]/</g.hitch/<()/3.8compact/ (line 172) .cache["dojo/aspect"]/</n/</h()/3.8compact/ (line 238) .cache["dojo/_base/lang"]/</g.hitch/<()/3.8compact/ (line 172) Reload the page to get source for: http://js.arcgis.com/3.8compact/" These error messages appear 4 times in a row. Here is my code:      function startGeocoder() {       geocoder = new Geocoder({        map : map,        arcgisGeocoder : {         placeholder : "Address search",         sourceCountry : "GBR"        }       }, "search");             geocoder.autoComplete = true;       geocoder.startup();       geocoder.on("select", queryLayer);           }           function queryLayer(evt){             popup.hide();       selectTariffLayer.clearSelection();       var point = evt.result.feature.geometry;       var query = Query();       query.geometry = point;       selectTariffLayer.selectFeatures(query, selectTariffLayer.SELECTION_NEW, function(results){        var charge = results[0].attributes["Charge"];        var price = results[0].attributes["Cost"];                 popup.setTitle("Parking tariffs");                 popup.setContent(charge + "<br/>" + price);                 popup.show(point);            });                       } Any suggestions where I'm going wrong?

Hi, I'm trying to convert coordinates from WGS84 to British National Grid using the geometry service but when I do this, the points all seem to be a bit out (maybe 100m or so). From reading up on this it seems that the reason is probably I'm not doing a datum transformation to the coordinates. However, I can't find out what value to put in for the datum transformation. The starting coordinates come from the geolocation API so are in WKID 4326, so the starting datum should be WGS1984 I think. The output spatial reference is British National Grid (WKID 27700) so it's datum is OSGB_1936. I've been searching to find out what the value for the datum transformation should be and the closest I've come is EPSG::1314 which is for WGS1984_To_OSGB_1936. I've tried specifying this as the datum transformation value but the output point is in the same location as if I leave this datum transformation parameter blank. Has anyone else come across this?    function zoomToLocation(location) {     var pt = new Point(location.coords.longitude, location.coords.latitude, new SpatialReference({      wkid : 4236     }));     var outSR = new SpatialReference({      wkid : 27700     });     var PrjParams = new ProjectParameters();     PrjParams.geometries = [pt];     PrjParams.outSR = outSR;     var datumtrans = 1314;     PrjParams.transformation = datumtrans;     geometryService.project(PrjParams, function(projectedPoints) {      console.log('Conversion completed. Datum Transformation: ' + datumtrans + '.');      pt = projectedPoints[0];      map.centerAndZoom(pt, 8);     });    } ... View more

Hi, I'm an ArcGIS Server Javascript API application that uses the buffer operation to buffer a point by 35m and finds features within that distance. The javascript API documentation recommends using a proxy page if doing buffer operations but then in the part in the javascript API documentation that explains the proxy page it says ???Common scenarios where you may run into URL length issues are when you use the buffer from a complex polygon as the input to a query task???. If I???m only buffering a point then would that run the risk of running into URL length issues? What is the URL that would be potentially long? And how can I test the length of the URL being created?

Hi, I'm trying to display a cached basemap and have a user click on it to create a new graphic point. All I really want at this stage are the coordinates of the point which will then be passed into another system. So far I've taken the sample for the compact api that displays a map and added a bit extra code to listen for a click and draw a point on the map at that location and show an alert with the coordinates of the point. It seems to work on a PC but when I use an android phone and add a point, the point displays in the top left hand corner of the original map starting location (even if I pan away from there and add a point). On android the alert box that displays the coordinates of the user click point then shows the x and y values as NaN. Here's my code, any suggestions as to what I'm doing wrong would be greatly appreciated.

Hi, On our website I want to embed a web map I've created with ArcGIS.com but I want the web map to have a table of contents that allows the user to turn on and off all of the layers in the map. Is it possible to turn layers on and off on the embedded web map? Are there any templates for it (I can't find one)? Thanks, Mike. ... View more
