How to get session->flashdata() working in HMVC module?

[eluser]helloworldly[/eluser]
Thanks.

A test in application/modules/module-name/controllers/module-name.php:

Code:

function function-name()
{
$this->session->set_flashdata('message', 'ERROR: hello world');
echo 'flash message = ' . $this->session->flashdata('message');
}

Which only works if the parent controller that loads this module (via ajax) has

Code:

$this->session->set_flashdata('message', 'ERROR: hello world');

otherwise 'message' is empty as it was never set it seems...
