Angular 2 Cannot find control with unspecified name attribute on formArrays
Remove the brackets from
[formArrayName]="areas" and use only
formArrayName="areas"This, because with [ ] you are trying to bind a variable, which this is not. Also notice your submit, it should be:
(ngSubmit)="onSubmit(areasForm.value)"instead of areasForm.values.
In my case I solved the issue by putting the name of the formControl in double and sinlge quotes so that it is interpreted as a string:
[formControlName]="'familyName'"similar to below:
formControlName="familyName"
The problem for me was that I had
[formControlName]=""Instead of
formControlName=""
