Angular2 - FormGroup include and exclude replacements in RC6

Question

include and exclude methods in FormGroup class were deprecated in RC5 and then removed in RC6.

So, how are we supposed to build conditional validation? We used to call include/exclude with form control name. Are addControl and removeControl an alternative?

Answer 1

In rc6 (and future versions) I've solved this issue by using AbstractControl enable and disable methods.

Example:

// before (rc5):
//this.formGroup.exclude('controlName');

// after (rc6):
this.formGroup.get('controlName').disable();

// before (rc5):
this.formGroup.include('controlName');

// after (rc6):
this.formGroup.get('controlName').enable();

Hope it helps you.
