Should it not be this.TextField = ref?

[ghost]

ref={(ref) => this.input = ref} this makes an issue when logging in then logging out directly after. Indeed, the email/password will remain in the input field but won't be taken into account when logging in again, giving an error message saying that email/password is required (while it's already filled in the input field).

the issue disappears with ref={(ref) => this.TextField = ref}
