Exception visiting the JSF component tree on restore state with unrendered components

[dhs]

Hi,

after restoring the state, webflow publishes an _post restore state_ event. That one visits the JSF tree. Is it the designated bahavior that the rendered flag of the components is ignored? I asumed that only rendered components will be visited, but I don't know the 'usages' of the _post restore state_ event...

In my project I get an NPE in a component that is not rendered.

The NPE does not occur if I change the publishing code in JSF2FlowApplication from:

  static void publishPostRestoreStateEvent() {
    FacesContext facesContext = FlowFacesContext.getCurrentInstance();
    try {
      facesContext.getViewRoot().visitTree(VisitContext.createVisitContext(facesContext),
          new PostRestoreStateEventVisitCallback());
    } catch (AbortProcessingException e) {
      facesContext.getApplication().publishEvent(facesContext, ExceptionQueuedEvent.class,
          new ExceptionQueuedEventContext(facesContext, e, null, facesContext.getCurrentPhaseId()));
    }
  }

to:

  static void publishPostRestoreStateEvent() {
    FacesContext facesContext = FlowFacesContext.getCurrentInstance();
    try {
      facesContext.getViewRoot().visitTree(VisitContext.createVisitContext(facesContext, null, EnumSet.of(VisitHint.SKIP_UNRENDERED)),
          new PostRestoreStateEventVisitCallback());
    } catch (AbortProcessingException e) {
      facesContext.getApplication().publishEvent(facesContext, ExceptionQueuedEvent.class,
          new ExceptionQueuedEventContext(facesContext, e, null, facesContext.getCurrentPhaseId()));
    }
  }
