GenerateRendererTask will work in custom featurelayer ?

[mohannainar1]

I have created custom feature layer and using it for GenerateRendererTask but nothing happening . My question is GenerateRendererTask will work in custom feature layer ? . If not what is the alternate method for doing class break renderer. I am attaching my code for reference.

Mohan,

  The GenerateRendererTask is limited by the requirement:

The GenerateRendererTask is available for map service or tables that support the generateDataClasses operation (version 10.1 or greater)

Your FeatureLayer is coming from a FeatureCollection and not a Map Service so it will not work.

So you just need to setup the ClassBreaksRenderer manually like in this sample:

Class breaks renderer | ArcGIS API for JavaScript 3.22
