init.js:327 [esri.core.Accessor] Accessor#set Assigning an instance of 'FlareClusterLayer' which is not a subclass of 'esri.Graphic' about flareclusterlayer HOT 6 CLOSED

Hi @YangZhenFang, sorry mate, not really enough detail in your issue to comment on fully.
Is the error occurring in your own version of the layer?
From the sounds of it you're trying to assign an instance of FlareClusterLayer to a graphic object, which obviously won't work as it's a layer not a graphic.
Are you using v3.x or v4.x?
Do you have an example page where this occurring?

Hi, sorry still can't really see what the issue is. Do you have a live example somewhere (jsfiddle, plunker) where it can be demonstrated?

As your coordinate fields are named Lat and Lng you'll need to set these properties in the constructor options when instantiating a FlareClusterLayer.

var fcl = new FlareClusterLayer({
   xPropertyName: "Lng",
   yPropertyName: "Lat"
});

sorry to bother you

Hi mate, I can't see anything wrong in the jsfiddle...but it doesn't run. Do you have a sample that runs that is displaying the error?
