Bind Value - How to use?

This is probably working as intended but I figured I would ask.

I am using a reactive form, my control value is an array of objects. When I use bingLabel, everything is fine. When I bindValue to a property within the objects, it throws an error.

ERROR Error: Binding object with bindValue is not allowed.

cities: = [
      {id: '1', name: 'Vilnius'},
      {id: '2', name: 'Kaunas'},
      {id: '3', name: 'Pavilnys'} 
  ];
     
  ngOnInit(){
      this.heroForm = this.fb.group({
          city: [this.cities]
      });
  }

<ng-select 
   [items]="cities"
   placeholder="Select city"
   bindValue="id"
   bindLabel="name"
   formControlName="city">
</ng-select>

Should I be able to bind to the property of an object such as bindValue="cities.id" or bindValue="city.id"?

I may be over thinking this, seems to work without the bindValue there at all but was curious why I was getting the error.

How can we preselect multiple objects?

I dont understand why they do this limitation??? if you remove the “warning” in the code in NgSelectComponent.prototype._isValidWriteValue to return true it works with objects just fine.

when this should be fixed alot of people here need to select objects…atleast let us work with the “compareWith” to recognize the object our self.
