Laravel 4.1 Facade非静态方法不应该静态调用

I am attempting to create a facade within laravel 4.1. I have created the facade, service provider and the class, to no avail. I followed numerous "how to's" including the advanced video for custom facades on Laracasts. No matter how many times I try, I end up with the exception of Non-static method Custom\Helpers\Helper::doSomething() should not be called statically

Here is my code...

HelpersServiceProvider.php

<?php namespace Custom\Helpers;

use Illuminate\Support\ServiceProvider;

class HelpersServiceProvider extends ServiceProvider {

    public function register()
    {
        $this->app->bind('trial','Custom\Helpers\Helper');
    }

}

HelpersFacade.php

<?php namespace Custom\Facades;

use Illuminate\Support\Facades\Facade;


class Helper extends Facade {

    protected static function getFacadeAccessor()
    {
        return 'trial';
    }

}

Helpers.php

<?php namespace Custom\Helpers;
class Helper {
     public function doSomething()
     {
        return 'Hello';
     }
}

I add the service provider to my app.php file and register the facade alias

'Custom\Helpers\HelpersServiceProvider',

'Helper'         => 'Custom\Facades\Helper',

Then when I try to access it via a Static call (yes, I know it's not really static) or via the service provider directly I get the exception error.

Scratching my head on this one...

It looks like you have an incorrectly named class (or file):

HelpersFacade.php

class Helper extends Facade {

Additionally, your Helper class is in Helpers.php. Those need to match, also.
