Hi,

I'm following this how-to on creating a custom editor, and as far as I Can tell I'm doing everything correct, but I just can't get it to work: http://umbraco.github.io/Belle/#/tutorials/Creating-Editors-Trees

My code class looks like this:

[PluginController("DataExport")]
  [Umbraco.Web.Trees.Tree("DataExport", "DataExportTree", "Data Export", iconClosed: "icon-doc")]
  public class DataExportTreeController : TreeController
  {
    protected override TreeNodeCollection GetTreeNodes(string id, FormDataCollection queryStrings)
    {
      var nodes = new TreeNodeCollection();

      var parentNode = CreateTreeNode("exportData", id, queryStrings, "Export Data", "icon-truck", false);

      nodes.Add(parentNode);

      return nodes;
    }

    protected override MenuItemCollection GetMenuForNode(string id, FormDataCollection queryStrings)
    {
      var menu = new MenuItemCollection();

      return menu;
    }
  }

My AngularJS controller code looks like this:

'use strict';

(function() {
  //create the controller
  function dataExportController($scope, $routeParams) {
    $scope.content = { tabs: [{ id: 1, label: "Export Organisation Data" }, { id: 2, label: "Export Member Data" }] };
  };

  //register the controller
  angular.module("umbraco").controller('DataExport.DataExportTree.EditController', dataExportController);
})();

and my edit.html view looks like this:

<div ng-controller="DataExport.DataExportTree.EditController">
  markup goes here...
</div>

My App_Plugins folder structure looks like this:

However, when I run Umbraco and navigate to my custom editor page I'm getting an error with the AngularJS Controller "Error: Argument 'DataExport.DataExportTree.EditController' is not a function, got undefined". If I take the ng-controller="DataExport.DataExportTree.EditController" tag out of my markup then the page renders with no errors (but obviously no AngularJS kicking in), so my tree configuration and paths all seem to be correct.

The tutorial doesn't mention anything about how the javascript file is picked up by Umbraco - do I need to reference this in a .manifest file or somewhere else?

Any clues would be greatly appreciated as I've been through this tutorial a few times now and I'm not getting anywhere... :s
