[TYPO3-mvc] How to get to typoscipt ?

[Tim Schoch | GSTALTIG]

Me again...

I'm experiencing another problem with my DI'd services, precisely my MailService. I'm trying to imiplement Bennys Mail Solution but with DI instead of extending another Class. (http://www.benny-vs-web.de/typo3/extbase-fluid-zum-rendern-von-e-mail-templates-verwenden/)

Heres my current Plain Text rendering method:
-------------------------------------
protected function getPlainTextEmailView() {
  // create another instance of Fluid
  $view = t3lib_div::makeInstance('Tx_Fluid_View_TemplateView');
    // set the controller context
  $controllerContext = $this->controller->buildControllerContext(); <- !! ERROR !! protected
  $controllerContext->setRequest( $this->controller->request ); <- !! ERROR !! protected
  $view->setControllerContext( $controllerContext );
    // this is the default template path
  $templatePath = t3lib_extMgm::extPath( $this->extensionKey ) . 'Resources/Private/Templates/Email/';
  $templateFile = $templatePath.$templateName.'.txt';
    // set the e-mail template
  $view->setTemplatePathAndFilename( $templateFile );
    // and return the new Fluid instance
  return $view;
}
-------------------------------------
$this->controller contains a reference to the calling controller. Not very nice, see my previous question.
But... all the controller stuff is protected. How do I access these settings?

Thanks, Tim
