Trying to Integrate 3.0 ClusterLayer

[MarkHoover]

Hello,

I'm trying to integrate the new ClusterLayer sample introduced at 3.0 (http://help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/layers_point_clustering.html) into my application but I'm having some problems with the dojo.require statement.

So, I've included the dojo.require("extras.Clusterlayer"); statement in my Default.aspx page.  But when I try to load my application with that statement included, it fails to load...I just end up with a blank page.  Then I saw this code in the sample:

<script>
var dojoConfig = {
parseOnLoad: true,
packages: [{
"name": "extras",
"location": location.pathname.replace(/\/[^/]+$/, '') + "/extras"
}]
};
</script> 

So I included it in mine and still nothing.  I realized the "location" property's pathname was probably incorrect, but I've tried everything I can think of, including setting "location" to "help.arcgis.com/en/webapi/javascript/arcgis/demos/layers/extras" which I assume is what it must be in the sample but no dice.

Can anyone instruct me on what I'm doing wrong here?  Thanks!

Indeed, simply copying the sample code and trying to run it locally produces the same problem.  Any assistance available?

ESRI, any help?

I just ran a quick test using the cluster sample code and was able to run it locally. Here are the steps I performed:
1. Downloaded the zip file containing the cluster code from here:
http://www.arcgis.com/home/item.html?id=4174dcae65bf42e1b776c17da4b279c1
2.Unzip the contents into a folder called cluster in  my web server root direction (c:/inetpub/wwwroot)
3.Test the app in my browser
http://localhost/cluster/layers_point_clustering.html

Indeed, simply copying the sample code and trying to run it locally produces the same problem.  Any assistance available?

This was discussed in a previous thread, but also make sure that your server environment is configured to serve .json, as that is how the point data for this sample is stored under the "/data" folder.

Finally got it working...aiming at the correct path to parse the extras library proved a pain, but it works!

Now then, I think there is a small fault in the extras/ClusterLayer.js file included in Esri's sample.  There is a line of code that says:

alert('Sorry, that cluster contains more than 1000 points.  Zoom in for more detail.');

I submit it should say:

alert('Sorry, that cluster contains more than ' + this._maxSingles + ' points. Zoom in for more detail.');

As maxSingles is an option provided to the user during configuration of a new ClusterLayer.

Thanks,
Mark

You're right, I'll make the change.

We made an update and missed adding the extras directory and ClusterLayer.js file to the download. I fixed this yesterday. Please re-download:  http://www.arcgis.com/sharing/content/items/1a6528fd3c774cfbbdf46df66c42958f/data
