I added a labelsOff function to the following "labeling features client-site" sample. In the console I get an error saying cannot find variable "labelsOff" which is the name of the function. What am I missing?

Finally solved this problem by changing the feature service rest endpoint url to the web adaptor Url. Http over 6080 was the problem. Working great now!

Not sure how to check the JSON response, unless you are referring to the response in the console. The message in the console is "syntax error" with no error code. [object Error]{description: "Syntax error", log: undefined, message: "Syntax error", name: "SyntaxError", number: -2146827286} I have successfully tested deletes and attribute updates at rest endpoint. Is there a way I can test a simple delete from the javascript application? I have a feeling that the proxy is the cause. Thanks.

Move and edit vertices | ArcGIS API for JavaScript and Editor widget | ArcGIS API for JavaScript I setup and tested the proxy.ashx page which appears to be working. The only error I am seeing (in the console) on creating features is a syntax error but with no error code. It appears that edits are being made to the database since I can move features (polygons) and update attributes, but as soon as I pan the map or refresh the page, the changes disappear. database: oracle AGS: 10.2 JSAPI: 3.15 Data is published with schema owner connection and feature service (Feature Access) selected with options checked to add, update, delete, etc. Thanks. Will

I am having some problems using the JS Editing samples. Features geometry changes are not being saved. After a page refresh the feature changes revert to the original size, location, etc. Thanks. -Will

I would like to snap 2 anchor points to a line in order to model the movement of an airplane (polygon) along a taxiway centerline. Is this possible or anyone have a workaround? Thanks. Will

I was able to get this to work by adding "return" before declare on line 4. define( ["dojo/_base/declare", "dojo/_base/lang", "esri/request"], function (declare, lang, esriRequest) { return declare(null, Without return I was seeing the same "not a constructor" error mentioned in the original post. It would be great if the Tutorial files were made available in the Samples or on GitHub. Thanks.

define( ["dojo/_base/declare", "dojo/_base/lang", "esri/request"], function (declare, lang, esriRequest) { declare(null, { distance: null, lastSearchResult: null, perPage: null, queryParams: null, seatGeekUrl: null, constructor: function (options) { // specify class defaults this.distance = options.distance || "20mi"; // default seat geek range is 30mi this.perPage = options.perPageage || 50; // default to 50 results per page this.seatGeekUrl = "http://api.seatgeek.com/2/events"; // returnEvents is called by an external function, esri.request // hitch() is used to provide the proper context so that returnEvents // will have access to the instance of this class this.returnEvents = lang.hitch(this, this.returnEvents); }, searchByLoc: function (geopoint) { var eventsResponse; this.queryParams = { "lat": geopoint.y, "lon": geopoint.x, "page": 1, "per_page": this.perPage, "range": this.distance } // seat geek endpoints: // petco park search using lat, lon: // http://api.seatgeek.com/2/events?lat=32.7078&lon=-117.157&range=20mi&callback=c // lat, lon for petco park: 32.7078, -117.157 eventsResponse = esriRequest({ "url": this.seatGeekUrl, "callbackParamName": "callback", "content": this.queryParams }); return eventsResponse.then(this.returnEvents, this.err); }, getMore: function() { var eventsResponse; // increment the page number this.queryParams.page++; eventsResponse = esri.request({ "url": this.seatGeekUrl, "callbackParamName": "callback", "content": this.queryParams }); return eventsResponse.then(this.returnEvents, this.err); }, returnEvents: function(response) { // check number of results if ( response.meta.total == 0) { // console.log("Seat Geek returned zero events: ", response); return null; } // save search result this.lastSearchResult = response; // console.log("set last search result: ", response, this); return response; }, err: function(err) { console.log("Failed to get results from Seat Geek due to an error: ", err); } }); });

Hey ESRI - It is the 4th Quarter already and there is still no Web AppBuilder / 10.3 release.

‎12-02-2014

This might be the answer - Flash Player 15 and Error 2032 for Flex Viewer

‎12-02-2014

So a workaround is to give users admin rights, so this issue is related to permissions. Is there a better solution than giving users Admin rights? I am using the 3.6 (api) flex viewer. Thanks. Will

‎11-25-2014

Is copying and pasting features supported in the flex viewer? I have some predefined shapes which need to be copied and pasted on the map. Thanks. Will

‎10-28-2014

Anyone made some videos on using the WebApp Builder?
