Hi @mnapoli

I am getting currently this error with PHP-DI 5.4.5:

Entry "Piwik\Plugins\CoreHome\FooBar" cannot be resolved: Parameter $customer of __construct() has no value defined or guessableFull definition:Object ( class = Piwik\Plugins\CoreHome\FooBar scope = singleton lazy = false __construct( $customer = #UNDEFINED# ))

when calling:

            return $container->make('Piwik\Plugins\CoreHome\FooBar', array(
                'customer' => $customer
            ));

and having a DI config like:

'Piwik\Plugins\CoreHome\FooBar' => DI\decorate(function ($customer, \Interop\Container\ContainerInterface $c) {

        $myTest = $c->get('test.vars.myTest');
        if (!empty($myTest)) {
            return new MyTest();
        }

        return $customer;
    }),

The class looks like this:

class FooBar {
    /**
     * @var array
     */
    private $customer;

    public function __construct($customer)
    {
        $this->customer = $customer;
    }

It works nicely as soon as I remove the DI\decorate() but not when I add it. It does not even go into the decorator when debugging it.

It fails in ObjectCreator::createInstance() with a DefinitionException.

It seems like the passed parameters get lost in DecoratorResolver::resolve(Definition $definition, array $parameters = []) where the $parameters are actually never used.
