Angular2-beta 17 - manually apply Validator

Question

We currenty have a legacy project, that needs to be maintained until the final version implementing angular-final is deployed.

In final I can easily apply conditional Validators using:

this.myForm.controls['name'].setValidators(Validators.required)

Obviously the set method was not available back then, the only exposed thing was

validator: ValidatorFN;

property on AbstractControl.

So following this, I tried setting it by just doing:

this.myForm.controls['someControl'].validator(Validators.required)

which will unfortunately throw the following error:

"Cannot read property 'validationViolations' of undefined"

because there is no explicit setter method you can set a new validator via this.myForm.controls['someControl'].validator=
