esri.ux.layers.ClusterLayer with latest JS API?

TimDine — Tue, 17 Sep 2013 16:37:49 GMT

Has anyone been able to make this work with the lastest JS API? I'm trying to make the sample work by only changing the api references and have started trying to convert the code, but am getting stumped pretty early.

dojo.declare('esri.ux.layers.ClusterLayer', esri.layers.GraphicsLayer, {

is right at the top in the declaration of the class and it blows up thinking the GraphicsLayer is "null or undefined".

Thoughts?

I'm trying to do the same thing and I'm having the same issue with that declare, any help would be greatly appreciated!

Got it to work to a degree:

used the following for esri.ux.layers.ClusterLayer-debug.js file.

define([

"dojo/_base/declare",

"esri/layers/GraphicsLayer",

"dojox/lang/functional",

"dojox/lang/functional/lambda",

"dojox/lang/functional/curry",

"dojox/lang/functional/fold"

], function (

declare, GraphicsLayer

) {

return declare([GraphicsLayer], {

constructor: function (options) {

... //rest of it like the esri.ux.layers.ClusterLayer-debug.js file

// sorry may not be allowed to post the rest of it due to company privacy

// please see below comments

});

Also at every "new esri.geometry.Point(...)" statement has to be converted to new esri.geometry.Point(..., this._map.spatialReference) where the spatial reference has to be specified, else it will default to 4326.

Also lot of the references to map was bombing out as null. I just replaced them with this._map which is being set in the constructor.

I was working on this today too. Looks like you got a lot further than this beginner (me) did.
I tried your solution and updated the index.html with

and receive a mulitpleDefine error. any ideas?

I created an updated version of the ClusterLayer that works with services, similar to a FeatureLayer, but with same added sugar.

You can read more about it here.

Here is a GeoNet blog post here

Thank you. That provided me with enough info to get esri.ux.layers.ClusterLayer-debug.js working with the latest JS API.
I'm just tracking down one last issue with mouse over infoWindows

Scripts, which you posted is very good, but thay haven't "flare effect". I need this functionality together with the script above. I'm novice in JavaScript and I can't do it. Can you give me some advice or can you implement this functionality? I think that for someone who knows how it will be easy.

Someone put together a FlareClusterLayer that may be what you are looking for.
