Hi

I am getting a JavaScript exception when selecting features from a FeatureLayer on the map. The selection *seems* to work (i.e the features are highlighted), however firebug reports this error:

dojo.io.script error Error: Deferred Cancelled

cancelResult: undefined
dojoType: "cancel"
fileName: http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.0

Firebug also reports the following error:


dojo.io.script.jsonp_dojoIoScript_postcodes00_0_02197265625_1_3 is undefined



Here is the code I am using:

I cannot afford to have JavaScript errors on the site I am working on, any help is greatly appreciated.
