Laravel whereHas not working in newQuery() - php

Question

I'm having some troubles getting a piece of code to work in laravel. I have a SecuredEloquent class that all my 'secured' models extend. what it does is simply add a whereHas clause to the query in the newQuery function I override:
class SecuredEloquent extends Eloquent
{
public function newQuery($excludeDeleted = true)
{
$query = parent::newQuery($excludeDeleted);
$context = App::make('Wall\Context\Context');
$query->whereHas('permissions', function($q) use ($context)
{
$q->where('context_id','=',$context->id());
$q->where('level','>=', $context->level());
});
return $query;
}
}
The problem: it doesn't work. I get "The connection was reset" errors in my browser and nothing in the log :( anyone any idea what I'm doing wrong?
edit2:
MyModel extends SecuredEloquent, OtherModel doesn't
When I try to run it in artisan tinker nothing happens.
var_dump(MyModel::all()); simply stops the process (it crashes? no idea, again nothing logged, it simply quits)
var_dump(OtherModel::all()); however simply works
edit:
I have ContextServiceProvider:
use Illuminate\Support\ServiceProvider;
class ContextServiceProvider extends ServiceProvider
{
/**
* Register
*/
public function register()
{
$this->app->singleton('Wall\Context\Context', function($app)
{
return new AppContext;
});
}
}
with AppContext:
use Illuminate\Database\Eloquent\Model;
class AppContext
{
/**
* The current context
*
* #var Illuminate\Database\Eloquent\Model
*/
protected $context;
/**
* The current context level
*
* #var int
*/
protected $level;
/**
* Check to see if the context has been set
*
* #return boolean
*/
public function has()
{
if($this->context) return true;
return false;
}
/**
* Get the context identifier
*
* #return integer
*/
public function id()
{
if ( $this->has() ) return $this->context->id;
return 0;
}
/**
* Get the context permission leven
*
* #return string
*/
public function level()
{
if ( $this->level ) return $this->level;
return 1;
}
}
Hope this helps
