IdentifyCallback / ExecuteIdentifyTask not returning results

[tylerjones1]

I am trying to display a popup based on the identify module. For some reason, my identify task is not returning results. Here is the code:

executeIdentifyTask: function (evt) {

            this.previewMode = false;  

            this.map.infoWindow.hide();

            this.map.infoWindow.clearFeatures();

            // don't identify on shift-click, ctrl-click or alt-click

            if (evt.shiftKey || evt.ctrlKey || evt.altKey) {

                return;

            }

            var mapPoint = evt.mapPoint;

            var identifyParams = this.createIdentifyParams(mapPoint);

            var identifies = [];

            var identifiedlayers = [];

            var selectedLayer = this.getSelectedLayer();

            array.forEach(this.layers, lang.hitch(this, function (layer) {

                var layerIds = this.getLayerIds(layer, selectedLayer);

                if (layerIds.length > 0) {

                    var params = lang.clone(identifyParams);

                    params.layerDefinitions = layer.ref.layerDefinitions;

                    params.layerIds = layerIds;

                    identifies.push(layer.identifyTask.execute(params));

                    identifiedlayers.push(layer);

                }

            }));

            if (identifies.length > 0) {

                this.map.infoWindow.setTitle(this.i18n.mapInfoWindow.identifyingTitle);

                this.map.infoWindow.setContent('<div class="loading"></div>');

                all(identifies).then(lang.hitch(this, 'identifyCallback', identifiedlayers, mapPoint), lang.hitch(this, 'identifyError'));

            } else {

                this.previewMode = true;

            }

        },

Could you also share the signature of the "identifyCallback". Does it has 3 parameters?

the syntax for the dojo/promise/all seems wrong. it should be something like

all(identifies).then( function(results){

     //here your code

});

but you seem to have replaced it with lang.hitch. but it does not have a error callback. may be thats what's wrong.

break inside the identifyCallback function and check the arguments parameter and check what values are returned.

[tylerjones1]

identifyCallback: function (identifiedlayers, mapPoint, responseArray)

check which parameter? IdentifiedLayers has a value, mapPoint has value, but responseArray is empty

[thejuskambi]

Sorry my bad, I wanted you to look at the arguments variable in the cosole.

quick question, the layer.identifyTask, are you adding this property to a esri Layer object, or it is your own object?

[tylerjones1]

I am adding esri/Tasks/IdentityTask.
