Can't use feature layers that have multiple symbol types / unique value infos

ShakilChoudhury — Thu, 15 Nov 2018 10:33:07 GMT

My layer looks like this:

Drawing Info:

Renderer:Unique Value Renderer:
Field 1: BLPU_CLASS
Field 2: null
Field 3: null
Field Delimiter: ,
Default Symbol: N/A

Default Label: null
UniqueValueInfos:

Value: CM03
Label: Hospital
Description:
Symbol:
Value: CX01
Label: Police Station
Description:
Symbol:
Value: CX02
Label: Fire Station
Description:
Symbol:

Transparency: 0
Labeling Info:

When using the feature layer like so:

var layer = new FeatureLayer({
url: "https://.../arcgis/rest/services/External_Maps/All_Data_Points/MapServer/6",
title: "...",
visible: false
});

I get this error in my console:

[esri.layers.FeatureLayer] [outFields] Invalid field: BLPU_CLASS

This occurs for any layer like above, with multiple symbol types on the layer. They appear in the layerlist but nothing is shown when I toggle the layer in question. Layers that only have one symbol type work fine as intended.

Shakil,

Try adding the outFields property to the constructor:

var layer = new FeatureLayer({
url: "https://.../arcgis/rest/services/External_Maps/All_Data_Points/MapServer/6",
title: "...",
visible: false,

outFields: ["*"]
});

I get a similar error with the same type of layer (multiple symbol types on the layer), but the layer it complains about for me is 'Creator'.

I have specified outFields in the constructor and still get this problem. Although I am not outputting all fields as shown in the example, I am only specifying a certain subset of fields that I need for popups to work properly.

William,

You also have to be sure you include any fields used in the renderer as well.
