Tom, I guess you can use dojo/promise/all in this scenario. zoomToFeature(feature){ return this.map.setExtent(feature.geometry.getExtent()) //assuming geometry is polyline or polygon }; var promises = []; features.forEach(function(gFeature){ promises.push(this.zoomToFeature(gFeature) .then(lang.hitch(this, this.sendToPrinter_SoilErosion)) .then(lang.hitch(this, this.zoombuffer)) .then(lang.hitch(this, this.sendToPrinter_SoilErosion))); }); all(promises).then(function(results){ console.log("all features printed"); }); Hopefully this will work not sure though. Just give it a try. -Girish

Chris, We have a Sign-In widget in WAB app which loads at the startup covering the app viewport. This widget ask for AGOL credentials and authenticate with the AGOL account that is set in the WAB configuration. _signIn: function(userName, password) { if(!userName || !password) return; var serverInfo = new ServerInfo(); serverInfo.server = this.appConfig.portalUrl; serverInfo.tokenServiceUrl = this.appConfig.portalUrl + "/sharing/rest/generateToken"; var userInfo = { username: userName, password: password } var def = window.esri.id.generateToken(serverInfo, userInfo); def.then( lang.hitch(this, this._signInComplete), lang.hitch(this, this._signInFailed)); } The benefits of using this design is that the user, roles and groups can be easily managed on AGOL or AGS. And Sign-In UI can be styled as desired. OAuth authentication can also be used but. We observed that OAuth authentication using IdentityManager does not provide much flexibility with the UI. Though IdentityManagerBase can be used to modify the style of the UI but it redirects to AGOL oauth, therefore the overlay effect is lost. -Girish

Mihkel, PrintTemplate.preserveScale = true; should solve this issue. -Girish

Iris, Assign a layerDefinition to the MapServiceLayer. -Girish

Shazia, The Legend dijit respect the layer visibility on the map. Therefore, if you just hide the FSM layer it should not be visible on the legend. The layer will NOT be removed from the map it will just be hidden. Layer.visible = false; OR Layer.hide(); -Girish

Tom, You need to remove the parentheses from the function call inside lang.hitch. Wrong notation: .then(lang.hitch(this, this.sendToPrinter_Test())); Correct notation: .then(lang.hitch(this, this.sendToPrinter_Test)); putting in parentheses is calling print function immediately. before the map extent gets change. -Girish

Oh, Is there any useful message in the proxy log file? If you haven't yet enabled it do it as follows: <ProxyConfig allowedReferers="*" mustMatch="true" logFile="proxylog.txt">

If alwaysUseProxy is set to false then set the proxyRules. Add your secured service url to the proxy rules: esri.urlUtils.addProxyRule({ proxyUrl : "https://mygisserver/arcgis/rest/services", urlPrefix : "https://appserver/proxy/proxy.ashx" }) -Girish

Chris, esri.config.defaults.io.useCors should be false or the default value "with-credentials" . if its true it will prevent the AJAX calls through proxy. -Girish

Chris, In the chrome's Developer Tools go to Network tab and check if the call to feature layer is going through proxy or not? something lilke this: https://appserver/proxy/proxy.ashx?https://mygisserver/arcgis/rest/services/base_services/test/MapServer/0 Also, are you setting the proxy url in esriConfig esriConfig.defaults.io.proxyUrl = "https://appserver/proxy/proxy.ashx " -Girish

oh yes, I quickly just compiled this code to show how can you change the infoWindow. However following is more complete example: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Popup</title> <link rel="stylesheet" href="https://js.arcgis.com/3.15/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="https://js.arcgis.com/3.15/esri/css/esri.css"> <style> html, body, #map { padding: 0; margin: 0; height: 100%; } /* Change color of icons to match bar chart and selection symbol */ .esriPopup.dark div.titleButton, .esriPopup.dark div.titlePane .title, .esriPopup.dark div.actionsPane .action { color: #A4CE67; } /* Additional customizations */ .esriPopup.dark .esriPopupWrapper { border: none; } .esriPopup .contentPane { text-align: center; } .esriViewPopup .gallery { margin: 0 auto; } </style> <script src="https://js.arcgis.com/3.15/"></script> <script> var map, defualtPopup; require([ "esri/map", "esri/dijit/Popup", "esri/dijit/InfoWindow", "esri/dijit/PopupTemplate", "esri/layers/FeatureLayer", "esri/symbols/SimpleFillSymbol", "esri/Color", "dojo/dom-class", "dojo/dom-construct", "dojo/on", "dojox/charting/Chart", "dojox/charting/themes/Dollar", "dojo/domReady!" ], function( Map, Popup, InfoWindow, PopupTemplate, FeatureLayer, SimpleFillSymbol, Color, domClass, domConstruct, on, Chart, theme ) { //The popup is the default info window so you only need to create the popup and //assign it to the map if you want to change default properties.

Hi Tracy, The InfoWindow and Popup are essentially same things. Popup is an implementation of InfoWindow that has few more features. Both are just a container therefore in most cases just changing the content (InfoWindow/Popup.setContent()) is enough. But if you have a custom popup/InfoWindow that you want to switch. Then use Map.setInfoWindow(customInfoWindow) This method is not mentioned in the API documentation but its there. here is a small example: This attaches an event handler on map click and check whether its clicked on any feature or not. If its not on any feature it changes the info window and its contents. you can insert any logic here. Or if you want the same thing can be done on Layer's OnClick also. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Popup</title> <link rel="stylesheet" href="https://js.arcgis.com/3.15/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="https://js.arcgis.com/3.15/esri/css/esri.css"> <style> html, body, #map { padding: 0; margin: 0; height: 100%; } /* Change color of icons to match bar chart and selection symbol */ .esriPopup.dark div.titleButton, .esriPopup.dark div.titlePane .title, .esriPopup.dark div.actionsPane .action { color: #A4CE67; } /* Additional customizations */ .esriPopup.dark .esriPopupWrapper { border: none; } .esriPopup .contentPane { text-align: center; } .esriViewPopup .gallery { margin: 0 auto; } </style> <script src="https://js.arcgis.com/3.15/"></script> <script> var map; require([ "esri/map", "esri/dijit/Popup", "esri/dijit/InfoWindow", "esri/dijit/PopupTemplate", "esri/layers/FeatureLayer", "esri/symbols/SimpleFillSymbol", "esri/Color", "dojo/dom-class", "dojo/dom-construct", "dojo/on", "dojox/charting/Chart", "dojox/charting/themes/Dollar", "dojo/domReady!" ], function( Map, Popup, InfoWindow, PopupTemplate, FeatureLayer, SimpleFillSymbol, Color, domClass, domConstruct, on, Chart, theme ) { //The popup is the default info window so you only need to create the popup and //assign it to the map if you want to change default properties.

Enjoy!

To access ArcGIS secured services through proxy without prompting for credentials. In the proxy.config add the <serverUrl> with credentials <serverUrl url="https://yourGISServer.domain/arcgis/rest/services/" matchAll="true" username="siteadmin" password="siteadmin"/> Note: When doing this its important to set the allowedReferers property as well to limit the access to the proxy itself. These are the esri proxy configurations mentioned on github: allowedReferers="http://server.com/app1,http://server.com/app2" : A comma-separated list of referer URLs. Only requests coming from referers in the list will be proxied. See https://github.com/Esri/resource-proxy/issues/282for detailed usage. username: Username to use when requesting a token - if needed for ArcGIS Server token based authentication. password: Password to use when requesting a token - if needed for ArcGIS Server token based authentication. Thanks, -Girish

Yeah, promises are a really cool stuff and much cleaner way to write asyc code. Now its gonna be in limelight in ArcGIS JS API 4.0

‎01-08-2016

You need to lang.hitch the calls to these functions to set the execution scope. add "dojo/_base/lang" to the imports and onTest: function () { this.zoombuffer() .then(lang.hitch(this, this.zoomselected)) .then(lang.hitch(this, this.zoombuffer)); }, -Girish
