The result is showing me four layers(3 polygon layers and 1 point layer). My main aim is to display the features on the map and be able to query them.</SPAN><BR /><SPAN>Currently I am using a JSON task, getting a json object , looping through all the features and storing them in graphics, adding them to a graphicLayer and displaying them. </SPAN><BR /><SPAN>My question is, </SPAN><BR /><SPAN>1. If i have to query for any feature or attribute then what kind of layer do I need to create from the data?</SPAN><BR /><SPAN>2. I am getting a featureSet through the following: </SPAN><BR /><SPAN>&nbsp; var myFeatureSet:FeatureSet = new FeatureSet(layers.featureCollection.layers<I>.featureSet.features);</I></SPAN><BR /><BR /><SPAN>3. But how to i get the layer details? I am using this line for now but it doesnt work..</SPAN><BR /><SPAN>var myLayerDetails:LayerDetails =&nbsp; layers.featureCollection.layers<I>.layerDefinition;</I></SPAN></BODY></HTML> Wed, 03 Jul 2013 06:21:41 GMT NigelDsouza 2013-07-03T06:21:41Z Feature layer from json https://community.esri.com/t5/arcgis-api-for-flex-questions/feature-layer-from-json/m-p/4067#M93 <HTML><HEAD></HEAD><BODY><SPAN>Hi I have been given a URL which gives the data in json format.
