Why is angular ignoring the validator?

Question

JavaScript

this.myform = new FormGroup({
      'name': new FormControl('', [
        Validators.required,
        Validators.minLength(3),
        Validators.maxLength(20)
      ]),
      'email': new FormControl('', [
        Validators.required,
        Validators.email
      ]),
      'password': new FormControl('', [
        Validators.required,
        Validators.pattern(/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/)
      ]),
      'password_repeat': new FormControl('', [
        Validators.required
      ])
    }, this.passwordMatchValidator)

the second argument to FormGroup is an additional validator that doesn't work at all. Tried { validator: this.passwordMatchValidator }, still ignores. Does this mean that if all controls have their own validators, then the additional one will be ignored?

Answer 1

this.myform = new FormGroup({ though it should, use this.formBuilder.group

constructor(private formBuilder: FormBuilder)  {}
    
ngOnInit() {
    this.myform = this.formBuilder.group({
        name: new FormControl('', [.....
           ....
        }, {
            validator:  myComponent.myGroupValidator
        })
}

static myGroupValidator(control: AbstractControl): { [key: string]: boolean } | null { 
    // тут в дебаге проверьте, что заходит сюда
    ....
}
