API 3.3 Measurement widget and wkid

MattLane — Tue, 15 Jan 2013 14:34:54 GMT

I've updated an app to vs 3.3 and am getting the following error with the measurement widget:
Uncaught TypeError: Cannot read property 'wkid' of undefined Measurement.js:19

I'm guessing the issue may lie with the basemap and all layers not being in web mercator, so I made a jsfiddle from the "Set custom extent and spatial reference" sample merged with the Measurement widget sample and got the same error.

It sounds like the issue from a past version of the api might be back

Matt,

I ran a quick test using your code and the measurement widget worked for me. I did have to add a geometry service so that the measurement widget could use it to project. Here's the revised code:

        //create map with new custom spatial reference and extent.  The map will be in the Goode Homolosine Land projection
        var map = new esri.Map("map", { extent: customExtentAndSR });
        
        dojo.connect(map, "onLoad", function(){
          var measurement = new esri.dijit.Measurement({
            map: map
          }, dojo.byId('measurementDiv'));
          measurement.startup();

Thanks for the reply, Kelly.

I copied your code to an updated fiddle and I still get the same error. I also made a page on my dev machine just to make sure that jsfiddle isn't the problem

Hi Matt,

In the code I provided earlier I also moved the logic to create the measurement widget until after the map loads. Here's a revised fiddle showing this:

Ah, I see. My 3.2 site didn't wait till the map was loaded and I never had an error. I made that change and it works now.

Thanks for the quick replies.
