Flashdata, language file and constructor [solved]

[eluser]Unknown[/eluser]
Howdy all! I'm new here and I have been working with CI few weeks now and I now I'm stuck with this little problem.

Main problem below is that flashdata goes thru, but it's empty. If I change 'login_access_rights' to something static text, it works just fine. So can I use (autoloaded) language file in controllers constructor if there is a redirect?

Code:

class Admin extends Controller {

    function Admin()
    {
        parent::Controller();    
        
        if(!$this->user_model->Secure(array('userType' => array('user','admin'))))
        {    
            $this->session->set_flashdata('flashError', $this->lang->line('login_access_rights'));
            redirect('login');    
        }
    }

Edit:
Problem solved, It had nothing to do with constructors, just poorly made stylesheet what made too long message disappear.
