patch Value in a nested form control using angular2

Question

I need to set a value in a nested control in a FormBuiler and the model is the following:

this.addAccForm = this.fb.group({
      accid: [\'\', Validators.re         


        

Answer 1

This did the trick for me:

this.addAccForm.patchValue({'cyc': {cycid: 1234567 }});
