When does ember destroy controller instances

Question

I was wondering when Ember does garbage collection for all the controller objects. I had route structure like :

AS.Router.map(function () {

            this.resource('employee', function () {
                this.route('basics');
                this.route('services');
                this.route('advanced');
            });

});

I have noticed that when I move from basics route to services route, the EmployeeBasicsController is not getting destroyed. I am not sure if it is by design, or I would have to do it manually(using the destroy action).

Answer 1

It's by design, Ember uses singleton instances by default.
