Controlling Nav (accessing Pages) from an Injectable service

I have an injectable service (OAuth2 client) and I want to log the user out and redirect them to a LoginPage when their access token is expired and refresh token is invalid/fails (see previous topic on handling refresh tokens here: https://forum.ionicframework.com/t/oauth2-api-calls-and-refreshing-tokens-chaining-observables/46671/5 )

I tried using IonicApp and app.getComponent('root-nav') to get my NavController, and that seemed to work fine, until I tried to call setRoot(LoginPage). Then it barfs and asks for LoginPage to be injectable.

import {IonicApp, NavController, Storage, SqlStorage} from 'ionic-framework';
import {LoginPage} from '../pages/login/login';

@Injectable()
export class WAC {
    constructor(http:Http, app:IonicApp) {
        this.http = http;
        this.app = app;
    }

    logout() {
        this.storage.remove('oauth');
        let nav = this.app.getComponent('root-nav');
        this.nav.setRoot(LoginPage);
    }
}

Thanks!
