No value accessor for form control

Question

I'm using Angular2-rc5, and I'm currently getting an error on my login page. I'm trying to make a form but the console throws exceptions telling me that it can't find my formcontrolls even though I create it on init. Any idea why I'm getting this error?

login component

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, FormBuilder, Validators } from '@angular/forms';
import { LoginService } from './login.service';
import { User } from '../../models/user';

@Component({
    selector: 'login',
    providers: [LoginService],
    templateUrl: './login.component.html',
    styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {
    private loginForm: FormGroup; // our model driven form
    private submitted: boolean; // keep track on whether form is submitted
    private events: any[] = []; // use later to display form changes

    constructor(private fb: FormBuilder, private ls:LoginService){
    }
    ngOnInit(){
        this.loginForm = new FormGroup({
            email: new FormControl('',[<any>Validators.required]),
            password: new FormControl('', [<any>Validators.required, <any>Validators.minLength(6)]),
            rememberMe: new FormControl()
        });
    }
    save(model: User, isValid: boolean) {
        console.log("Test");
        console.log(model, isValid);
    }
    // Login in user
    login(email: any, password: any){
        this.ls.login(email, password, false); 
    }
}

Exception

EXCEPTION: Uncaught (in promise): Error: Error in ./LoginComponent class LoginComponent - inline template:13:45 caused by: No value accessor for form control with name: 'email'.....

Answer 1

You are adding the formControlName to the label and not the input.

You have this:

<div >
  <div class="input-field col s12">
    <input id="email" type="email"> 
    <label class="center-align" for="email" formControlName="email">Email</label>
  </div>
</div>

Try using this:

<div >
  <div class="input-field col s12">
    <input id="email" type="email" formControlName="email"> 
    <label class="center-align" for="email">Email</label>
  </div>
</div>

Update the other input fields as well.

For UnitTest angular 2 with angular material you have to add MatSelectModule module in imports section.

import { MatSelectModule } from '@angular/material';

beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ CreateUserComponent ],
      imports : [ReactiveFormsModule,        
        MatSelectModule,
        MatAutocompleteModule,......

      ],
      providers: [.........]
    })
    .compileComponents();
  }));

In my case, I used Angular forms with contenteditable elements like div and had similar problems before.

I wrote ng-contenteditable module to resolve this problem.
