angular2-busy not working when calling Observer.error()

[samih-dev]

Hi,

I'm having the following code testing the module:

`import { Component, OnInit } from '@angular/core';
import { Subscription } from "rxjs/Subscription";
import { Observable } from "rxjs/Observable";
import { Observer } from "rxjs/Observer";
import { IBusyConfig } from "angular2-busy";
import 'rxjs/add/operator/delay';

@component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
busyConfigSettings: IBusyConfig
busy: Subscription;
ngOnInit(){

this.busyConfigSettings = {
  delay: 0,
  minDuration: 0,
  message: 'loading...',
  busy: null,

}

this.busyConfigSettings.busy = this.generateObservable().subscribe(
  () => { // success
    console.log('logic for success');
  },
  () => { // error 
    console.log('logic for error');
  },
  () => { // complete
    console.log('logic for compelete');
  });

}

generateObservable(): Observable{
return Observable.create((observer: Observer) => {
observer.error("Notify about error, expecting loader to be hidden after this.");
// observer.next(null);
observer.complete();
}).delay(5000);
}
}
`

calling Observer.next is working as expected, but when trying to call observer error, loading isn't showing at all, and sometimes I got exception regarding the change detection for Angular.

Any help? seems not supported.
