Angular 2 Form “Cannot find control with path”

Question

I try to make a dynamic form (so you can limitless add items to a list), but somehow the content of my list is not getting send because it can\'t find the control with path:

Answer 1

I also encountered this error, and I solved this problem by initiating the variables of class(elements in this.fb.array([])).

Code Snippet

    mobileNumbers: this.fb.array([this.fb.group(new MobileNumber('IN'))]),

Where class MobileNumber is used.

export class MobileNumber{
    public country_code: string;
    public mobile_number: string;
    constructor($cc){
        this.country_code = COUNTRY_CODES[$cc];
    }
}

To

export class MobileNumber{
    public country_code = '';
    public mobile_number = '';
    constructor($cc){
        this.country_code = COUNTRY_CODES[$cc];
    }
}
