Print Task: cannot read property of 'query' of undefined

davidrenz — Tue, 17 Feb 2015 04:58:07 GMT

Hello,

I am trying to wire up some print functionality on an app that I am building.

I basically just copied the code from the JSAPI samples page ... just to get a sense of how it works,

When I click on the "Print" button, it heads off like the samples do, but I get the following error:

js.arcgis.com/3.12/esri/tasks/Geoprocessor.js?1424148233374:14 Uncaught TypeError: Cannot read property 'query' of undefined

I am not sure how to resolve this, it is the first time I have used the 10.2 print task.

I have also tried to publish my own templates as a print task and that is getting the same error.

Could someone point me in the right direction on this?

thx

David

Code is below:

doPrint: function() {

console.log("In the startup for print!");

//esriConfig.defaults.io.alwaysUseProxy = false;

//esriConfig.defaults.io.proxyUrl = "";

// get print templates from the export web map task

var printInfo = esriRequest({

"url": this.printUrl,

"content": { "f": "json" }

});

printInfo.then(this.handlePrintInfo, this.handleError);

handlePrintInfo: function (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.preserveScale = true;

plate.format = "PDF";

plate.layoutOptions = {

"authorText": "Made by: Esri's JS API Team",

"copyrightText": "<copyright info here>",

"legendLayers": [],

"titleText": "Pool Permits",

"scalebarUnit": "Miles"

};

return plate;

});

// create the print dijit

var printer = new Print({

"map": global.MAP, // ---> yes, I know <sigh!>

"templates": templates,

url: this.printUrl

}, dom.byId("print_button"));

try {

printer.startup();

}

catch (ex) {

console.log(ex.message);

}

printer.on('print-start', function () {

console.log('The print operation has started');

});

printer.on('print-complete', function (evt) {

console.log('The url to the print image is : ' + evt.result.url);

});

I could really use a hand on this.

If someone could give me a hand, I would totally appreciate it.

When I run the print task and watch it in Fiddler, I get this::

# Result Protocol Host URL Body Caching Content-Type Process Comments Custom

2 304 HTTP www.currymap.org /arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task?f=json 0 private, must-revalidate, max-age=0 chrome:888

This is the error I am getting: --> it means nothing to me except that it keeps pointing back to the Geoprocessor.js file. Could this be a permissions or config issue?

Hopefully a working sample will help you. I'm not sure on yours, but I based my working code on Esri's print task sample too. I have a working sample that I built off of our own web services here: Print a Map

Click the Hammer

Click the Printer

And then you can print from there

The source code is here: JS Bin - Collaborative JavaScript Debugging

hmmm .... your code worked with my map services and print service. cool!

Well, I guess I will use your stuff on this. I am not sure why the ESRI example code is not working with it, but whatever.

thx Chris!

Your example helped me see what I was NOT doing correctly.

So, thanks for taking the time to help me out .. it is very much appreciated.
