What is going wrong here is hat the lc_item component is rendering an plain webapp based url, not a PortletURL. The /cedar/setURL.do is invoked as is and thus not resulting in a portlet invokation... What you need to do is modifying the lc_item component to transform its url to a StrutsPortlet url using the StrutsPortletURL class. Normally within a Struts Portlet application, this is automatically handled by the extended struts tags (html:link, html:rewrite etc.). You can do that yourself by calling StrutsPortletURL.createActionURL(request, path) or .createRenderURL(request, path).
