Has something changed in the last 2-3 days?

BenCamp — Wed, 18 Feb 2015 22:15:51 GMT

All of a sudden - with no code update from me - the symbols for the identifytask on my web application have stopped rendering. Has anyone else experienced this?

Do you have a public site or can you post your code here or on jsbin ?

Does this help?

function initFunctionality () {

map.on("click", doIdentify);

identifyTask = new IdentifyTask("SERVICEURL");

identifyParams = new IdentifyParameters();

identifyParams.tolerance = 10;

identifyParams.returnGeometry = true;

identifyParams.layerIds = [0,3,5,7,10,11,14,22,25,26];

identifyParams.layerOption = IdentifyParameters.LAYER_OPTION_ALL;

identifyParams.width = map.width;

identifyParams.height = map.height;

symbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID,

new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,

new Color([143, 73, 102]), 2),

new Color([143, 73, 102, 0.25]));

//if there are url params zoom to location

var coords, zoomLevel;

var urlObject = esri.urlToObject(document.location.href);

if(urlObject.query && urlObject.query.coords && urlObject.query.zoomLevel){

var coords = urlObject.query.coords.split(',');

var lon = parseFloat(coords[0]);

var lat = parseFloat(coords[1]);

var zoomLevel = parseInt(urlObject.query.zoomLevel);

var point = esri.geometry.geographicToWebMercator(new esri.geometry.Point(lon,lat));

map.centerAndZoom(point,zoomLevel);

}

For me it would help if the full JavaScript were there including your require statements and web services. Are you able to post the whole page?

Hey Chris,

Thanks for the offer to help. Take a look at this page. This is the code I've used in my application as well. And it appears no geometry is symbolized in this example either.

I'm not totally following this example here: Display identify results in popup | ArcGIS API for JavaScript but it does highlight a parcel using the identify task. I just don't see how it selects. Any ideas Rene Rubalcava‌ ?

I copied the code from that page and tested it out.

First thing I saw was that you are not returning geometry with the IdentifyResult.

identifyParams.returnGeometry = false;

I changed it to true.

Second thing I noticed was the results are not actually added to the map. They are saved to a cityResults and countyResults, but then nothing is done with them.

I don't know what logic you wanted for adding the graphic, so I just tweaked the code in a JSBin to do this.

Hope that helps.

Thanks.

OK thank you both for your help. I've hesitated to share my application because frankly I have no experience coding in javascript and basically take the examples from the ESRI site and hammer them until I get them to operate as I need. However, as I mentioned, in the last couple days my application has stopped "highlighting" identified features. Seems strange and I'm at my wits end. Would you mind taking a look (take it easy on my obviously poor coding skills)?

I see the symbolization when I use the Map Search button, but not when I click on a building on the map. Looking at your code, I don't see the showResults (or showResults2) being called when you execute the IdentifyTask.

One other negligible thing...you call the "dijit/registry" module twice in your require line (with duplicate "registry" variables in the function). Also, why call "dojo/_base/connect" when you never use it?

Thanks for the note about dijit/registry

Even when I call showResults2 it doesn't render the geometry. I think I'm losing my mind.

I can't really test it, but if you look at the Esri sample, the symbology for selected items is set in the Popup that is passed to the map.

You could also try manually setting the symbology in your doIdentify method.

feature.setSymbol(symbol); // you define symbol near the top

I'm not sure why it was working and stopped working for you, but I think either of the above solutions should do the trick... I think.

Thank you everyone for the responses. I think I've tracked the change to some setting in my map service. If I look back at an older version of my app that is referencing a different service the symbology works as expected. I will investigate some change in the service.

Thanks again.
