An error has occurred: TypeError - Unable to read the property 'push' of undefined
addAddress() {
const control = <FormArray>this.AddUserstep2Form.controls['addresses'];
const addrCtrl = this.initAddress();
control.push(addrCtrl);
}
initAddress() {
return this.fb.group({
stateCode: [''],
cityId: ['']
});
}
This issue arises when the control variable is null. To fix it, make sure to initialize it as an empty array.
const control = <FormArray>this.AddUserstep2Form.controls['addresses'];
const addrCtrl = this.initAddress();
if(control && control.length > 0){
control.push(addrCtrl);
} else {
control = [];
control.push(addrCtrl);
