Unable to load class "Symfony\Bundle\AsseticBundle\DefaultValueSupplier"

[kniziol]

composer update, Symfony 2.8.x-dev

1. I removed new Symfony\Bundle\AsseticBundle\AsseticBundle() because of error:
   PHP Fatal error: Class 'Symfony\Bundle\AsseticBundle\AsseticBundle' not found in .../app/AppKernel.php on line ...

2. The next error shows up:
   Unable to load class "Symfony\Bundle\AsseticBundle\DefaultValueSupplier"

What should I do now?

Please ask support questions on stackoverflow. It looks like you might not have assetic bundle as a dependency in your composer.json.

Yes, I haven't, because, as I wrote, I removed new Symfony\Bundle\AsseticBundle\AsseticBundle() because of error:
PHP Fatal error: Class 'Symfony\Bundle\AsseticBundle\AsseticBundle' not found in .../app/AppKernel.php on line ...

AsseticBundle was removed:
symfony/symfony-standard@2bee277

1. What should I do now?
2. Why AsseticBundle was removed?

@kniziol It just means that AsseticBundle isn't included by default in the Symfony Standard Edition but you are completely free to add it to your project.

@xabbuh Thanks, it's one of possible solutions. Is there any doc describing why AsseticBundle was removed?
