Leaflet & Esri-Leaflet: JSON objects not drawing correctly when using 'fields' filter

Question

I am working with Leaflet 0.7.3 and esri-leaflet beta.6. Using L.esri.Layers.FeatureLayer works fine until I add the fields filter. At that point, the geojson objects draw sporadically (mostly not at all). I might see one or two shapes on the screen.

Example code at http://codepen.io/BBurnworth/pen/fhBrG/

Lines 32-36:

 //The line below works.
 var parcels = new L.esri.Layers.FeatureLayer(url + '24');

 // **The below line works (Checked JSON attributes in firebug) but the parcels flicker and don't display properly**
 // var parcels = new L.esri.Layers.FeatureLayer(url + '24', { fields: "CITY" });

Is this a bug or am I leaving something out? The JSON (in Firebug) reads correctly, with the geometry data coming in. It just doesn't draw correctly.

I would love for someone to point out something simple that I am missing. I would rather fetch just the bare minimum of data and then use the tasks.IdentifyFeatures to get the attribute data when the user wants it.

Answer 1

a couple things here...

1. that constructor option expects an array

2. at a minimum, you have to include the OBJECTID field in that array in order for everything to work on the clientside as it should.

   { fields: ["OBJECTID", "CITY"] }

we should probably be handling that for people. i'll look into it.
