Router resolves undefined values when building with "ng build --prod"

[Humberd]

What is wrong?

I'm using @angular/cli and when I build a project using ng build --prod all the values that I resolve in all the states are returning undefined values.

When I build using ng serve or ng build everything works fine.

Steps to recreate

I created this repo that shows the problem.

I created a home component:

@Component({
  moduleId: module.id,
  template: `Hello: {{foo}}`
})
export class HomeComponent implements OnInit {
  @Input() foo: string;

  constructor() {
  }

  ngOnInit() {
  }
}

In the app.module I created a default home state for that component:

export function resolveFn() {
  return () => {
    return "bar";
  }
}

let state: Ng2StateDeclaration = {
  name: "home",
  url: "/home",
  component: HomeComponent,
  resolve: [{
    token: "foo",
    resolveFn: resolveFn
  }],

};

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    UIRouterModule.forRoot({
      states: [state],
      otherwise: "home"
    })
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

In the app.component.html I added ui-view directive:

<h1>
  APP COMPONENT
</h1>
<div ui-view></div>

How does it look using ng serve

How does it look using ng build --prod

@Humberd see #36. It's fixed in 1.0.0-beta.5 which hasn't been released yet. You'll need to use @ResolveData() instead of @Input() to decorate your input.

or just wait for angular 4 no need to use @ResolveData(), the only workaround right now is to downgrade the @ngtools/webpack version

I updated the @angular/cli to the newest version 1.0.0-rc.2 and I can inject the input to the constructor like this:

export class HomeComponent implements OnInit {
  constructor(@Inject("foo") private foo: string) {
  }

  ngOnInit() {
  }
}

This should be working in latest ui-router using @Input() foo: string;, although injecting is also fine.
