angular - Angular2 Router: Cannot find primary outlet to load 'HomeComponent' -

-

tried switch new router in version "@angular/router": "3.0.0-beta.2" in combination "@angular/*": "2.0.0-rc.4", following official docs on componentrouter.

however, i'm facing issue when trying load app default homecomponent:

cannot find primary outlet load 'homecomponent'

it seems has using templateurl , external html file instead of using inline template style.

homecomponent not shown in window , error printed console. however, when use link home component gets shown second hand.

as change from

templateurl: 'home.html'

to

template: '<router-outlet></router-outlet>'

error gone, homecomponent shown , routing works expected.

is known issue? work using templateurl? there have respect work?

the problem was, due app loading screen, <router-outlet></router-outlet> did not exist yet, due race condition. if need hide html part containing outlet, use [hidden] instead of *ngif, ensure outlet in dom , not removed conditionally.
