How to get FormControl instance from ControlValueAccessor

Question

I\'ve the following component:

@Component({
    selector: \'pc-radio-button\',
    templateUrl: \'./radio-button.component.html\',
    providers: [
        {         


        

Answer 1

Goes from my answer of this stackblitz question

Another solution is add as provider NG_VALIDATORS. So, in our function validate we can store the control in a variable

public validate(c: FormControl) {
  if (!this.control)
    this.control=c;
  return null;
