Using the new 'data' option for CakeEmail attachments with CakePHP 2.4.x

Question

The CakeEmail help page states that the data option has been added as of 2.4, so you no long have to have a physical file to add an attachment to an email.

I've got the following code:

$Email->from(array($this->Session->read('Auth.User.email') => $this->Session->read('Auth.User.name')))
->to($this->request->data['email-to'])
->subject($this->request->data['email-subject'])
->attachments(array('attachement1.pdf', array('data' => $pdf)))
->send($this->request->data['email-message']);

But whenever I run that I get an Internal Error saying File Not Found: "".

I had a look at the source code (which I'm beginning to learn is often more useful than reading the documentation!): https://github.com/cakephp/cakephp/blob/master/lib/Cake/Network/Email/CakeEmail.php

Changing my code to:

$Email = new CakeEmail('default');
$Email->from(array($this->Session->read('Auth.User.email') => $this->Session->read('Auth.User.name')))
->to($this->request->data['email-to'])
->subject($this->request->data['email-subject'])
->attachments(array('attachement1.pdf' => array('data' => $pdf, 'mimetype' => 'application/pdf')))
->send($this->request->data['email-message']);

Notice on the attachments line, the array is assigned to the filename variable, rather than passed in as a parameter!

For completeness, if anyone else is reading this and is wondering how I am generating my PDF with CakePDF:

// Create PDF for attachment
$CakePdf = new CakePdf();
$CakePdf->template('claim', 'default');
//get the pdf string returned
$pdf = $CakePdf->output();
