“Exception: Error during instantiation of t! Primary outlet already registered.” in cordova angular2 app

问题

I am building an simple cordova app with my project. It has 2 levels of nesting (main route) -> child route -> (another child route). When trying to browse to the 2nd level (another child route) I get an error saying Exception: Error during instantiation of t! Primary outlet already registered. First level works fine. I have not used router outlet twice in any template. The issue is the same in the emulation of browser as well as android.

Attached the chrome inspect below.

My build source structure:

My main component:

import {Component} from 'angular2/core';
import {ApproutesComponent} from '../app/approutes';
import {ROUTER_DIRECTIVES, ROUTER_PROVIDERS, RouteConfig} from 'angular2/router';

@RouteConfig([
  {path: '/d/...', component: ApproutesComponent, name: 'ApproutesCmp', useAsDefault:true}
])
@Component({
  selector: 'main-app',
  templateUrl: 'app/r/main/rmain.html',
  directives:[ROUTER_DIRECTIVES]
})
export class RroutesComponent {
  constructor(){}
}

I had the same problem with angular2 beta11, just not using cordova.

According to a post here you should use the non-minified version of router.js. Sounds strange, but it worked for me.
