Current behavior I use ReactiveFormsModule and when i add formControl to multi select element i can’t make it working. I get this error:

core.umd.js:3462 EXCEPTION: Uncaught (in promise): Error: Error in http://localhost:3000/app/components/category.component.js class CategoryComponent - inline template:0:1701 caused by: values.map is not a function

Expected behavior I should use formControl to bind the multi select selected items to a variable. For example i could add to the select tag [formControl]="myForm.controls.cities" and get all selected items in myForm.controls.cities.value.

Minimal reproduction of the problem with instructions If i use select it works with no problems:

        <select class="ui fluid dropdown" [formControl]="myForm.controls.category">
            <option *ngFor="let item of categories" value="{{item}}">{{item}}</option>
        </select>

If i use select multiple it doesn’t work:

        <select multiple="" class="ui fluid dropdown" [formControl]="myForm.controls.category">
            <option *ngFor="let item of categories" value="{{item}}">{{item}}</option>
        </select>

Here is a Plunker

What is the motivation / use case for changing the behavior? The use case is a select menu in which users can select more than choice.
