how to bind app.service property to the view?

[MurhafSousli]

Hi, I'm trying to use app.service to get/set global loading state.
in app.html I print the loadState, {{loadState}} which supposed to be bound to appState.get().loadState

<div class="app-inner">
  loading : {{loadState}}
  <header></header>
  <main layout="column" layout-fill>
    <router-outlet></router-outlet>
  </main>
</div>

app.ts

export class App{

  constructor(public appState: AppState) {
    this.appState.set('loadState', false);  //initial value.
  }
  get loadState() {
    return this.appState.get().loadState;
  }
}

however I'm getting this error: EXCEPTION: Expression 'loading: {{loadState}} in App@0:23' has changed after it was checked. Previous value: 'false'. Current value: 'true' in [loading: {{loadState}} in App@0:23]

the error is clear, but I can't figure out how to fix it? am I using app.service the wrong way?

I'm going to change the angular2-hmr api and remove the getter so it's not confusing

sorry this may sound super rule but I'm closing long standing issues and refactoring the codebase. If you run into this problem again feel free to open another issue
