Fuel block params

Gumster

I'm not sure if this is a bug or misuse, but here's my issue:

Inside a controller Reservations, I'm using a view inside of the email class message() method like so

$content = $this->load->view('reservations/reservation_response_email', ['data' => $data], TRUE);
$this->email->message($content);

In that view I'm using fuel_block() to pull in some partials and parse any braced variables (provided above by $data). So that works as intended just fine, but I get a PHP error too:

<br />A PHP Error was encountered

Severity: 4096

Message: Object of class Reservations could not be converted to string

Filename: libraries/Parser.php

Line Number: 150

The fuel_block is being used so:

fuel_block(['parse' => TRUE, 'view' => 'reservation_request_'.$data['request']], $data, FALSE);

I need to send parameters to fuel_block(), as if I don't specify parse => TRUE it won't parse the braced variables, while if I just set the first argument to fuel_block() as the view name, I don't get the error.

Somehow the Parser helper or class is referencing the controller class ($this) but I don't know what I need to do to prevent that? I can suppress the error with @fuel_block() of course, but that makes me feel bad.
