Print widget implementation : TypeError issue with PrintTask.js

Question

This print widget is blocked before creating an output. The combobox properly retrieves the print task url, but the console shows "TypeError: b is undefined" for http://js.arcgis.com/3.17/esri/tasks/PrintTask.js:25:13. Map is created in Map.js var map; var baseMapLayerWorld; require([ "esri/map", "esri/dijit/Search", "esri/layers/ArcGISDynamicMapServiceLayer","esri/layers/FeatureLayer", "esri/InfoTemplate", "dojo/domReady!" ], function (Map, Search, DynamicMapServiceLayer, FeatureLayer, InfoTemplate) { baseMapLayerWorld = new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer"); map = new Map("map", { center: [-150, -17], // lon, lat zoom: 8 }); map.addLayers([baseMapLayerWorld); }); The print widget is implemented in Print.js: var app = {}; require([ "esri/map", "esri/layers/FeatureLayer", "esri/dijit/Print", "esri/tasks/PrintTemplate", "esri/request", "esri/config", "dojo/_base/array", "dojo/dom", "dojo/parser", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!" ], function( Map, FeatureLayer, Print, PrintTemplate, esriRequest, esriConfig, arrayUtils, dom, parser ) { parser.parse(); app.printUrl = "https://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export Web Map Task"; esriConfig.defaults.io.proxyUrl = "http://our-server/Java/proxy.jsp"; // get print templates from the export web map task var printInfo = esriRequest({ "url": app.printUrl, "content": { "f": "json" } }); printInfo.then(handlePrintInfo, handleError); function handlePrintInfo(resp) { var layoutTemplate, templateNames, mapOnlyIndex, templates; layoutTemplate = arrayUtils.filter(resp.parameters, function(param, idx) { return param.name === "Layout_Template"; }); if ( layoutTemplate.length === 0 ) { console.log("print service parameters name for templates must be \"Layout_Template\""); return; } templateNames = layoutTemplate[0].choiceList; // remove the MAP_ONLY template then add it to the end of the list of templates mapOnlyIndex = arrayUtils.indexOf(templateNames, "MAP_ONLY"); if ( mapOnlyIndex > -1 ) { var mapOnly = templateNames.splice(mapOnlyIndex, mapOnlyIndex + 1)[0]; templateNames.push(mapOnly); } // create a print template for each choice templates = arrayUtils.map(templateNames, function(ch) { var plate = new PrintTemplate(); plate.layout = plate.label = ch; plate.format = "PDF"; plate.layoutOptions = { "authorText": "Made by: Esri's JS API Team", "copyrightText": "", "legendLayers": [], "titleText": "Pool Permits", "scalebarUnit": "Miles" }; return plate; }); // create the print dijit app.printer = new Print({ "map": app.map, "templates": templates, url: app.printUrl }, dom.byId("print_button")); app.printer.startup(); } function handleError(err) { console.log("Something broke: ", err); } }); They come together in the index.html:

Print Templates Created from Info Returned by the Print Service using esri.request

Note: This sample uses an ArcGIS Server version 10.1 export web map task.

Print templates are generated from the Export Web Map Task's Layout_Template parameter. This info is retrieved from the service using esri.request.

Good Morning Nhu,

If your basemapLayerWorld is Tiled, then you should use certainly ArcGISTiledMapServiceLayer

but you haven't load the Module in your require.

You mix up legacy module definitions like "new esri.layers.ArcGISTiledMapServiceLayer"

with AMD-Style by using require.

This was what i meant.

So your Project loads, you can choose the Layout, but when you want to Print by using the Button, you get an error, right?

Have you check your console, if the Print is sent correctly?

Hi Miriam,

The baseMapLayerWorld was intended to be a tiled map service layer to act as the map's basemap. I'm hesitating to do what you suggest by adding this layer as a dynamic map service--should this make a difference for map loading?

I've added the other requirements, but still get a TypeError related to PrintTask.js

You forgot to declare

"dijit/layout/BorderContainer", "dijit/layout/ContentPane"

in your require. Maybe to complete your require is all that you need.

Also you made a mistake when setup your DynamicMapServiceLayer.
Instead of

baseMapLayerWorld = new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer");

you should use the require for the ArcGISTiledMapServiceLayer you load above :baseMapLayerWorld = new DynamicMapServiceLayer("http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer");
