conditionalExpression im FormArray

[elvispdosreis]

I need to use a conditional validator where I need to get the value of a variable out of context

table: [null, [RxwebValidators.required({conditionalExpression:(x)=> x.firstName == 'John'})]]

ngOnInit() {
        this.userInfoFormGroup = this.formBuilder.group({
          firstName:['',[RxwebValidators.required()]],
          lastName:['',[RxwebValidators.required({conditionalExpression:(x)=> x.firstName == 'John'})]]
          prices: this.formBuilder.array([
                this.formBuilder.group({
                    table: [null, [RxwebValidators.required({conditionalExpression:(x)=> x.firstName == 'John'})]],
            ]),
        });
}
