title: Laravel 5 withInput old always empty
body: <p>I'm building a simple login form using Laravel 5 and I would like to fill some inputs by default when some error occurred. 
  My router is calling these functions as given</p>
  
  <pre><code>Route::get('/login','AuthController@login');
  Route::post('/login','AuthController@do_login');
  </code></pre>
  
  <p>My Controller is like showed below</p>
  
  <pre><code>namespace App\Http\Controllers;
  use App;
  use App\Models\User;
  use Request;
  use Illuminate\Support\Facades\Redirect;
  
  class AuthController extends Controller {
  
     function login()
     {
         if(User::check())
         {
             /*User is logged, then cannot login*/
             return Redirect::back();
         }
         else
         {
             return view('auth.login');
         }
     }
      function do_login()
      {
          return view('auth.login')-&gt;withInput(Request::except("password"));
      }
  
  }
  </code></pre>
  
  <p>Noticing that withInput is being underlined by PhpStorm saying that can't find it's implementation in Illuminate\View\View.
  Inside my view, i have the following:</p>
  
  <pre><code>            {!! Form::open() !!}
              &lt;div class="form-group"&gt;
                  {!! Form::text('email', Input::old('email'), array('placeholder' =&gt; Lang::get('auth.email'), 'class' =&gt; 'form-control')) !!}
              &lt;/div&gt;
              &lt;div class="form-group"&gt;
                  {!! Form::password('password', array('placeholder' =&gt; Lang::get('auth.password'),'class'=&gt;'form-control')) !!}
              &lt;/div&gt;
              &lt;div class="form-group"&gt;
                  &lt;button class="btn btn-primary btn-block"&gt;@lang('auth.signin')&lt;/button&gt;
                  &lt;span class="pull-right"&gt;&lt;a href="/{{App::getLocale()}}/register"&gt;@lang('auth.register')&lt;/a&gt;&lt;/span&gt;
              &lt;/div&gt;
          &lt;input type="email" class="form-control" name="email" value="{{ old('email') }}"&gt;
          {!! Form::close() !!}
  </code></pre>
  
  <p>What am I missing here? This can be done in Laravel 5 ?
  Many thanks for your time!</p>
