I\'m new in angular 2 and i try to make a reactive form but i have some trouble. After many search in stack i found no solutions.

Here you can see my error

Answer 1

Don't use userForm = new FormGroup()

Use form = new FormGroup() instead.

And in the form use <form [formGroup]="form"> ...</form>. It works for me with angular 6
