3.10 label layer change not working?

WalterEralio — Thu, 04 Sep 2014 13:07:06 GMT

Upgrading to 3.10 I found in the documentation at what's new ( What's new in Version 3.10 | Guide | ArcGIS API for JavaScript )

Label layer changes: Labeling expressions no longer use ${field} syntax but now use {field}. In other words, popup template syntax instead of info template syntax.

I've changed it accordingly and the {CASENUMBER} text is displayed instead of the value

lomaLabels.addFeatureLayer(featureLayerLOMA, lomaLabelRenderer, "{CASENUMBER}" ,{pointPriorities:"AboveLeft"});

I really need this since I'm struggling with ${} been confused with a TAG and my program blows out with the error org.apache.jasper.JasperException: The attribute prefix CASENUMBER does not correspond to any imported tag library

Walter,

try this:

var labelField = "CASENUMBER";

lomaLabels.addFeatureLayer(featureLayerLOMA, lomaLabelRenderer, "{" + labelField + "}" ,{pointPriorities:"AboveLeft"});

Let me know if it works.

Tim

Tim,

I need some help figuring this out, I am trying to do something similar, but once I add the label layer, the feature layer is not showing up.

I have added this, among other required

require ([ "esri/layers/LabelLayer",

"esri/renderers/ScaleDependentRenderer"

function( LabelLayer, ScaleDependentRenderer

var featureLayer = new FeatureLayer("http://services1.arcgis.com/hVMNhMnY75fwfIFy/ArcGIS/rest/services/NursingFacilities/FeatureServe mode: FeatureLayer.MODE_ONDEMAND,

outFields: [labelField]

});

var labelField = "FacilityID";

var NFColor = new Color("#444")

// create a text symbol to define the style of labels

var NFLabel = new TextSymbol().setColor(NFColor);

NFLabel.font.setSize("12pt");

NFLabel.font.setFamily("arial");

NFLabelRenderer = new SimpleRenderer(NFLabel);

var labels = new LabelLayer({

id: "labels" });

// tell the label layer to label the Nursing facility feature layer

// using the field named "FacilityID"

labels.addFeatureLayer(featureLayer, NFLabelRenderer, "{" + labelField + "}");

// add the label layer to the map

map.addLayer(labels);

// scale dependent renderer for NF labels

var NFRenderer = new SimpleRenderer(NFLabel);

var NFScaleDependent = new ScaleDependentRenderer({

rendererInfos: [{

renderer: NFRenderer,

minScale: 500000,

maxScale: 1

);

});

var NFOptions = { pointPriorities: "AboveCenter" };

labels.addFeatureLayer(featureLayer, NFScaleDependent, "{FacilityID}", NFOptions);

FeatureLayer.setRenderer(NFRenderer);

map.addLayer(featureLayer);

The feature layer itself is not loading, something is missing or I am not doing it right, any help will be appreciated.

Thanks!

Saloni,

in your code there is an "r" missing here:

http://services1.arcgis.com/hVMNhMnY75fwfIFy/ArcGIS/rest/services/NursingFacilities/FeatureServe

use this link instead

http://services1.arcgis.com/hVMNhMnY75fwfIFy/ArcGIS/rest/services/NursingFacilities/FeatureServer

let me know if this is the issue.

Tim,

I added the correct link, but that did not help, probably something else needs to corrected, still working on it.

Thanks for the help.
