</fieldset>
        }
        }

but it doesnt showing the email of a person set in email session field value. I tried to google it out but unable to get anything Any help would be appreciated

Answer 1

Just create a... new User object and set required values WITHOUT saving it to DB in the controller (pseudo code!):

User user = new User();
user.email = session("email");
Form<User> userForm = Form.form(User.class);
return ok(newUserView.render(userForm.fill(user));

Benefit: using this approach + several conditions in the view you can use single view for creating/editing users.
