Chris Czerniak​ asks.. How did you bring up the controller data on google debugger?

[Jon Barnes]

quick way to see angular scope data is to do this:

1. select an element in your page, right-click and click Inspect.

2. then when the developer tools comes up, select the console tab, and type angular.element($0).scope().

3. The above will give the scope of the currently selected element.

4. if you want the scope of the current widget, you may have to navigate the $parent objects in your object to get to the widget scope. or, look for your widget in the html elements tab and select it, then type the above in your console to get straight to the scope of the selected element, which would be your widget.

Hint: in the html markup, widgets will generally look something like this:

<div id="xb9f86f98db690300ff4975131f9619c4" class="va167a398db690300ff4975131f9619a7 ng-scope" data="data" options="options" widget="widget" server="server">

I know this is an old comment, but for someone stumbling here in future, one could also find a couple of Context Menus stating

"Log to Console $scope" and "Log to Console $scope.data" when one CTRL + Right_Clicks on the widget instance in Portal.
