How to inject a service into every component in Ember JS

I have a session service that I want to inject into every component, according to the docs, this should work:

app.register('service:session', Session, { singleton: true });
app.inject('controller', 'session', 'service:session');
app.inject('route', 'session', 'service:session');
app.inject('component', 'session', 'service:session');

It works for controllers and routes, but generated components do not pick up the service.

How can I make this work?

I know that some are going to say that giving a component access to a service is bad form, but then again, the Ember core team are advising that controllers are going to be replaced by route-able components and in which case it seems perfectly reasonable.

I am following this technique to shim route-able components in the meantime: http://ift.tt/21UuFRN
