CI seems to load twice

[eluser]Y0shi[/eluser]
Hello there,

I've just written another function on my project which is coded with CI. My only one core class outputs something twice:

Core class header

Code:

class MY_Coresystem extends CI_Controller {

    function MY_Coresystem()
    {        
        parent::__construct();

Troublesome code

Code:

$output = $this->load->view('widgets/'.$element->sidebar_widget, '', TRUE);
    $this->template->write($element->sidebar_location, $output);

General controller header

Code:

class Article extends MY_Coresystem {

    function Article()
    {
        parent::MY_Coresystem();

So to summarize: When the page is being rendered, the content of widgets/widget.php is outputtet twice... Does anyone of you have general thoughts? Thanks in advance.
