actionResponse.sendRedirect(url) not working

Question

I have one portlet which has a commandLink. On the actionListner of commandLink I called the backingBean.

The backing bean has the following code.

ActionResponse actionResponse = (ActionResponse) LiferayFacesContext.getInstance().
     getExternalContext().getResponse();
actionResponse.sendRedirect("http://localhost:8080/web/guest/pageName");

I have a redirect to the another portlet page. Both portlets are contained in a single war.

This redirection is not working, it gives: classCastException. can't clast to ActionResponse

I have also tried for,

ActionResponse actionResponse= (ActionResponse) FacesContext.getCurrentInstance().
    getExternalContext().getResponse();
actionResponse.sendRedirect("http://localhost:8080/web/guest/pageName");

It Throws ClassCastException. Can not cast to ActionResponse

Exception StackTrace :

Please try this link,

http://www.portletfaces.org/community/forums/-/message_boards/view_message/76606

and code,

in your jsp or xhtml,

<h:commandButton id="btn1" type="submit" action="#{bean.redirectAction}" value="test redirect ajax" />

in your bean,

 public void redirectAction() {
   System.out.println("Action Triggrered");
    try {


        Map<String, Object> reqestMap = FacesContext.getCurrentInstance().getExternalContext().getRequestMap();
        ThemeDisplay themeDisplay = (ThemeDisplay) reqestMap.get("THEME_DISPLAY");
             FacesContext.getCurrentInstance().getExternalContext().redirect(themeDisplay.getPortalURL() + "/web/{user-id}/home");
          } catch (IOException e) {
             // TODO Auto-generated catch block
            e.printStackTrace();
         }
      }

I was facing this problem as well. Used the above solution but was not working. Later identified that, it is the problem with the liferay's portletfaces-bridge jar. I was actually using portletfaces-bridge-2.0.0.jar, but this issue got resolved in portletfaces-bridge-2.0.1.jar.

Try to use portletfaces-bridge-2.0.1.jar. and the above code will work.

If this is not working for you. Then, check if you are using GenericFacesportlet. In that case, you have to use Liferay 6.0.6.
