Hi!

It seems, that the service-manager doesn’t care anymore, if a service was initiated or not.

Example of my Module.php:

```php

    public function getControllerConfig()
    {
        return [
            'factories' => [
                Brand\Controller\JsonDataController::class => function ($container) {
                    $ctrl = new Brand\Controller\JsonDataController();
                    $ctrl->setBrandTable($container->get(BrandTable::class));
                    return $ctrl;
                },
         ];
     }

```

But `BrandTable` was never initiated. Doesn’t this trigger an error, sth. like “Service not found. Are you sure you mapped it to factory?”

I’m confused.

Hey Malwon,

in this scenario `BrandTable::class` results into a string of the fully qualified classname. It is not an instance of the `BrandTable` object. The service manager may result into null in your case. This indicates, that you have registered `BrandTable::class` somewhere in your config already. You could solve this by type hinting the controller constructor method like the following example:

```auto
<?php

declare(strict_types=1);

namespace Marcel\Controller;

class MyController
{
    public function __construct(
        protected BrandTable $table
    ) {}

    ...
}

```

In this case the controller awaits an instance of `BrandTable`. If this is not given it will result into an error in any case.

Hi ezkimo,

thanks for caring to answer.

> You could solve this by type hinting the controller constructor method like the following example

I actually did type hinting.

> This indicates, that you have registered `BrandTable::class` somewhere in your config already.

No, I didn’t.

**I jut now tried the following to demonstrate what I mean:**

This is my folder structure:  
 ![Screenshot_20230922_223320](https://canada1.discourse-cdn.com/flex032/uploads/zendframework/original/2X/5/5418bbe33bfee2fdaca4ee24d5213cf64e524f72.png)

My Module.php:

```php
public function getControllerConfig()
    {
        return [
            'factories' => [
                Controller\IndexController::class => function ($container) {
                    $ctrl = new Controller\IndexController;
                    $ctrl->setFoo($container->get(Model\Foo::class));
                    return $ctrl;
                }
            ]
        ];
    }

```

My Controller:

```php
class IndexController extends AbstractActionController
{

    protected Foo $foo;

    public function indexAction()
    {
        return new ViewModel();
    }

    /**
     * Set the value of foo
     *
     * @param Foo $foo
     *
     * @return self
     */
    public function setFoo(Foo $foo): self
    {
        $this->foo = $foo;

        return $this;
    }
}

```

This works! But actually it shouldn’t, cause I never provided a factory for my `Foo`-model.

Why **doesn’t** it throw this usual error:

> Unable to resolve service “Application\Model\Foo” to a factory; are you certain you provided it during configuration?

🤔

Please check if an abstract factory is registered in your application which handles the creation of the class `Foo`. Search for `abstract_factories` in your code.

@Tyrsson I don’t know why you deleted your post, because it’s the solution! Fortunately, your original reply is still readable. 😄 For some reason, I just must have pressed “yes” when the laminas-mvc installation-routine asked me about Laminas\Di.

Removing ` 'Laminas\Di'` from `config/modules.config.php` helped. And now the error:

> Unable to resolve service “Application\Model\Foo” to a factory; are you certain you provided it during configuration?

is thrown, as it is supposed to be, isn’t it?

Thank you man, and all others that posted their suggestions.

laminas-di comes with a registered abstract factory:

@malwon, This error-solving technique has really made someone a real deep-thinking developer. Now, someone can build an entire framework on his own or even a module in Laminas MVC. This is really helpful. Thanks!

Can’t remember why I removed it…

Lamians-Di has caused many issues like this. It caused me a major issue using Laminas-Authentication since it autowired an instance when laminas-auth does not provide a factory. Honestly, in my opinion it should be removed from the list of dependencies that is offered in the create-project routine.

Please create an issue report or a pull request for it, otherwise your opinion will be lost.
