Fpm.navigate - using the FPM to redirect application to a new URL

Question

Hello All,
Has anyone managed to successfully used the fpm navigate method to cause the application to close and open a URL when the application is not running in a portal?
I tried to do the following in the onInit of my Fc, but got an error in that the FPMComponentWindowInterfaceView controller was not instantiated...
     NavigationTarget restartURL =
     new NavigationTarget(                         
     null,
     NavigationTarget.NAVIGATION_TYPE_URL,
     null,
     null,
     null,
     true,
     themeURL,
     null,
     null,
     null,
     null,
     WDPortalNavigationMode.SHOW_INPLACE,
     null);
     fpm.navigate(restartURL);
error occurs in the FPM code of com.sap.pcuigp.xssfpm.wd.Navigation.java:
if (exitUrl != null && !"".equals(exitUrl)) {
     if ("".equals(windowTarget)) {
          // replace current application with navigation target in same browser window
          wdThis.wdGetFPMComponentWindowInterfaceViewController().wdFirePlugExitPlug(exitUrl);
     } else {
     // open navigation target in new browser window; different targets are not supported by WD
          IWDWindow window =
          wdThis.wdGetAPI().getComponent().getWindowManager().createExternalWindow(exitUrl, text, false);
          window.setWindowPosition(WDWindowPos.CENTER);
          window.open();
the
wdThis.wdGetFPMComponentWindowInterfaceViewController()
fails.
Has anyone else managed to get this method to work? Is there something I should be doing before executing my code? I would have thought that as this interface view controller is the one that all FPM apps use as a starting point, that it would be instantiated...
Help/ideas appreciated.
Thanks,
Chris

No response was ever forthcoming - I'm not sure if the same issue still exists - but I'm going to close this off as I really can't be sure it is still relevant.
