Symfony Sonata Formatter demo issue

This repo was created to explain bug report in Sonata Formatter

sonata-project/SonataFormatterBundle#669

Getting Started

1. If not already done, install Docker Compose
2. Run docker-compose build --pull --no-cache to build fresh images
3. Run docker-compose up (the logs will be displayed in the current shell)
4. Run symfony server:start
5. Run php bin/console doctrine:database:create
6. Run php bin/console doctrine:schema:update --force
7. Run bin/console ckeditor:install
8. Run in/console assets:install
9. Run docker-compose down --remove-orphans to stop the Docker containers.

Reproduce bug

• Navigate to https://127.0.0.1:8000/admin/app/article/create
• Click on image icon in FCK editor
• Click on Browse Server window with error opens "Sonata\FormatterBundle\Controller\CkeditorAdminController" has no container set, did you forget to define it as a service subscriber?"
• Navigate to upload tab select file and click upload - error message is displayed inline "Sonata\FormatterBundle\Controller\CkeditorAdminController" has no container set, did you forget to define it as a service subscriber?"

Notes

1. check in symfony/framework-bundle/Controller/ControllerResolver.php

    `if ($controller instanceof ContainerAwareInterface) {
        $controller->setContainer($this->container);
    }
    if ($controller instanceof AbstractController) {
        if (null === $previousContainer = $controller->setContainer($this->container)) {
            throw new \LogicException(sprintf('"%s" has no container set, did you forget to define it as a service subscriber?', $class));
        } else {
            $controller->setContainer($previousContainer);
        }
    }`
   

   fails because the container is not set in Sonata\FormatterBundle\Controller\CkeditorAdminController

2. CkeditorAdminController does not implement ContainerAwareInterface

3. Container is not injected in any other way during the initialization

4. I didn't find in the sonata formatter docs information describing a way or a need to inject container manually
