TypeScript-'s Angular Framework Error - “There is no directive with exportAs set to ngForm”

Question

I keep getting this error while using TypeScript\'s Angular2-forms framework:

There is no directive with \"exportAs\" set to \"ngForm

Answer 1

In case a name is assigned like this:

#editForm="testForm"

... the exportAs has to be defined in the component decorator:

selector: 'test-form',
templateUrl: './test-form.component.html',
styleUrls: ['./test-form.component.scss'],
exportAs: 'testForm'
