[TYPO3-english] Call a controller action from a form Postprocessor

[Sergio Catalá]

Does anyone know how to redirect to a controller action from a form 
mailpostprocessor class (e.g. extends 
\TYPO3\CMS\Form\PostProcess\MailPostProcessor)?

I tried to inject there my controller and call the action method 
directly and it goes inside, but the objects that are initialized 
(through "initializeAction") in the action controller are not injected.

Any hint?
