[fw-general] appendScript doesn't work

[Markus Hausammann]

Hi

I'm doing this in my action:

$chartLoader = 'swfobject.embedSWF("open-flash-chart.swf", "mainRadar",
"550", "200", "9.0.0", "expressInstall.swf",
{"data-file":"project-charts/main-radar.php"} );';

$this->view->headScript()->appendScript($chartLoader, $type =
'text/javascript');

in my layout I include:

<?php echo $this->headScript(); ?>

which should render the appended script into the head which happens but like
that:

<script type="text/javascript">
    //<![CDATA[
swfobject.embedSWF("open-flash-chart.swf", "mainRadar", "550", "200",
"9.0.0", "expressInstall.swf", {"data-file":"project-charts/main-radar.php"}
);    //]]>
</script>

how can I get rid of the //<![CDATA[ stuff?

Thank you!
Markus
