ngModel cannot be used to register form controls with a parent formGroup directive

Question

After upgrading to RC5 we began getting this error:

ngModel cannot be used to register form controls with a parent formGroup 
 directive.
Try using formGroup\         


        

Answer 1

I just got this error because I did not enclose all my form controls within a div with a formGroup attribute.

For example, this will throw an error

This can be quite easy to miss if its a particularly long form.
