Description
Hi,
after restoring the state, webflow publishes an post restore state event (in JsfViewFactory.getView()) . That one visits the JSF tree. Is it the designated bahavior that the rendered flag of the components is ignored while visting? 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:
JSF2FlowApplication.java
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:
JSF2FlowApplication.java
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())); } }
Thank you
