Phalcon\Mvc\View\Simple::render() in mailer causing WSOD - phalcon

Question

I have a simple controller action that creates a Guest record and renders a template.
// First bind the form to our Guest:
$form->bind( $_POST, $guest );
// Validate and save, or show error messages
if( $form->isValid($_POST, $guest) ) {
if( $guest->save($_POST) ) {
$this->view->setMainView( 'confirm' );
}
}
This works fine before I add any mailer stuff. However, when I add an event handler inside the Guest model which happens to render a template, the controller renders a WHITE SCREEN OF DEATH instead of my confirm template.
In Guest model:
public function afterCreate() {
return GuestMailer::sendEmailConfirmation( $this );
}
In GuestMailer class:
public static function sendEmailConfirmation( $guest ) {
// create/configure $email message
$view = $guest->getDI()->get('simpleView');
$view->render( // Works without this call...
'confirmation_email',
array( 'guest' => $guest )
);
$content = $view->getContent();
$email->content( $content );
return $email->send();
}
Note that when I remove the above call to render(), the confirm template is rendered successfully.
I thought components in Phalcon were supposed to be highly decoupled? Why is rendering a completely different template causing my controller's view to get messed up? How can I avoid this?

I think this problem is caused by a peculiar configuration of the templating service, in a normal workflow it doesn't causes issues, they appears when you need to render "manually" a template as in your case, you can refer to this PhalconPHP forum discussion linked, in particular the answer refered by the link anchor:
