This seems like such a simple task but after an hour I still can't figure it out.

It's just a login page, and I can login just fine, but in case of error I want the email address to persist. I'm calling "withInput();" on the redirect but in the Twig template no matter what variable I use, I can't seem to get it to work. The name of the field is "email"

Controller:

catch (Cartalyst\Sentry\Users\WrongPasswordException $e)
{
    $error = 'Wrong password, try again.';
    return Redirect::back()->withInput()->withErrors($error);
}

View:

{{ input.email }}
{{ input.old.email }}
{{ Session_get('email') }}
{{ input.old }}
{{ email }}
{{ input  }}
{{ input_old.email }} 
{{ old.email }}

In Blade it looks like you call "input::old('email')" but that throws an exception in Twig.
