Error in the preview of invoice

Hi Nicolas,

when I try to print the invoice of one of my orders I see this error in the preview window

Fatal error: Call to a member function get() on a non-object in /web/htdocs/www.hidesign.it/home/components/com_hikashop/views/order/tmpl/show.php on line 163

If you download again the install package on our website and install it, it should fix the problem. It was fixed a few days after the release of 1.5.4
