Symfony2 can't find tempalte file
===

I am having issues using twig templates for email in SF2.

First, I created a template file located at:
`MainBundle/Resources/views/Email/InviteNewUsers.twig`

Next, I rendered the view as the body of my email: `$this->get('mailer')->send($this->renderView('MainBundle:Email:InviteNewUsers.twig', array('code' => $invite->getCode())));`

Unfortunately, this triggers an error: `Unable to find template "MainBundle:Email:InviteNewUsers.twig"`


is there something wrong with my file placement or my render command?
