Ok, thanks for your response.
I watch for EventSubscriber because I want to manage the post_bind case.
But if I bind my event subscriber to formBuilder I cannot take other
service. This is the reason because I want to use eventListener: I can
create a service that has services I want (ie Monolog).
Have you any idea how I can do that?
