Programmatically navigate to page

Question

Hello,
I am trying to navigate to a page whenever any exception occurred. I have the following managed bean:
public class EstimationController extends BaseWebController {
    private EstimateService estimateService;
    private EstimateHomeDataBean estimateHome;
    public EstimationController() {
        super();       
        init();
    private void init() {       
        try {
            estimateService = getEstimateService();
            estimateHome = getEstimateHome();    
        } catch(Throwable thrown){
            Log.error(this, thrown.getMessage(), thrown);
            manageError();
}For this I have defined the control-flow-rule in adfc-config.xml as:
<control-flow-rule id="__10">
    <from-activity-id id="__9">*</from-activity-id>
    <control-flow-case id="__12">
      <from-outcome id="__13">gotoPartError</from-outcome>
      <to-activity-id id="__11">partError</to-activity-id>
    </control-flow-case>
</control-flow-rule>the manageError() method has been defined in BaseWebController withing which I have tried many of the following codes, nothing is working:
getFacesContext().responseComplete();
getFacesContext().getApplication().getNavigationHandler().handleNavigation(getFacesContext(), null, "gotoPartError");
getFacesContext().renderResponse();
getServletResponse().sendRedirect("/partError.jspx"); 
getFacesContext().getExternalContext().redirect(getServletRequest().getContextPath() + "/pages/partError.jspx");
RequestDispatcher dispatcher = getServletRequest().getRequestDispatcher("partError.jspx");           
dispatcher.forward(getServletRequest(), getServletResponse());
FacesContext context = FacesContext.getCurrentInstance();           
UIViewRoot newPage = context.getApplication().getViewHandler().createView(context, "/partError.jspx");
context.setViewRoot(newPage);
context.renderResponse();
ControllerContext.getInstance().getCurrentViewPort().setViewId("partError");My requirement is to navigate programmatically to the error page whenever any exception is occurred in the managed bean, and so I cannot define error pages in web.xml. My application can generate two types of exception and so depending on the exception type I need to navigate any of the two error pages I have.
Any suggestion would be very helpful.
Thanks in advance.

try java script...
public void navigateToErrorPage(){
ExtendedRenderKitService service =
Service.getRenderKitService(FacesContext.getCurrentInstance(),
ExtendedRenderKitService.class);
String page = "window.open('/partEerror.jspx','_self')";
StringBuffer navigatePage = new StringBuffer();
navigatePage.append("var hints = new Object();");
service.addScript(FacesContext.getCurrentInstance(),
page);
call this in your manageError() method...
