Point Clustering with a customer layer

WeipingZeng — Tue, 19 Jun 2012 17:09:25 GMT

The point clustering with a customer layer is a new sample in version 3.0. But it seems that the codes do not work. I downloaded the source and associated codes (see the url below) and put them on C:\inetpub\wwwroot folder. Unlike the live sample, the codes show only a base map without any points. Did I miss something?

The data used for clustering is in a .json file. Is your IIS instance configured to serve JSON?

I downloaded the whole zip, uncompressed it and it works fine but ONLY in Safari. I am getting a bunch of errors on Firebug when I tried to load it on Firefox and in Chrome it just doesn't show. I need some help here too!!! Thanks in advance!

What are the specific errors you're seeing? Do you see the same errors when you load the copy of the sample we host: http://help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/layers_point_clustering.html

Browsers tested:
�?� Safari Version 5.1.7 (7534.57.2)
�?� Google Chrome Version 19.0.1084.56
�?� Mozilla Firefox Version 13.0.1

The tests were run on Mac OS X v. 10.7.4 and Windows 7 Professional Service Pack 1.

I was actually trying to load the layers_point_clustering.html file contained in the unzipped esri_js_api_clustering_sample package available in the samples (unmodified). Only Safari was capable of showing the map. Running Firefox with the Firebug plugin reported the following error:

Error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://serverapi.arcgisonline.com/jsapi/arcgis/?v=3.0 :: <TOP_LEVEL> :: line 15" data: no]
http://serverapi.arcgisonline.com/jsapi/arcgis/?v=3.0
Line 15

On the other hand, when I uploaded the files to my apache repository and opened the HTML, the maps displayed correctly in all the browsers.

Thanks for the quick response.

PS: And I have no issues when loading the hosted sample

I think your latest testing points to an issue with your web server. Again, I would check that your IIS instance is configured to serve JSON.
