            Client reports success with this workaround:

            public static void checkViewRoot(PersistentFacesState state, String viewId) {
                     FacesContext ctx = state.getFacesContext();
                     if (ctx.getViewRoot() == null) {
                         UIViewRoot viewRoot = ctx.getApplication().getViewHandler().createView(ctx, viewId);
                         if (viewRoot != null) {
                             ctx.setViewRoot(viewRoot);
                         }
                     }
                 }


            There may be future problems with this as a full JSF lifecycle is not running.

            Description

            Client has a long running process trying to do navigation. With the introduction of StateSaving, the ViewRoot is no longer maintained between user requests.

            The PersistentFacesState class has been modified to keep a reference to the information required to start a JSF lifecycle. This is necessary for all server push operations but in this case, the navigateTo and redirectTo methods don't start a JSF lifecycle and the client hasn't the means to start one in the long running thread hence the ViewRoot reference will be null.
