Hi again.... :)
I have a little question about receiving the FacesContext from a Servelt...
so my problem is - sometimes (only sometimes, but often enough ;) ) when
click on a file
to download I get the following error:
2007-05-16 17:20:28,812 ERROR

At the moment I try to resolve the FacesContext these way:
protected FacesContext getFacesContext(HttpServletRequest request,
HttpServletResponse response) {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext == null) {
logger.debug("~~~~~~~~~~~~~~~~~~~ FacesContext is null,
trying another
way...");
FacesContextFactory contextFactory =
(FacesContextFactory) FactoryFinder
.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
LifecycleFactory lifecycleFactory = (LifecycleFactory)
FactoryFinder
.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
Lifecycle lifecycle = lifecycleFactory
.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
facesContext =
contextFactory.getFacesContext(request.getSession()
.getServletContext(), request,
response, lifecycle);
}
return facesContext;
}
and here the Error happens:
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
FacesContext fctx = getFacesContext(request, response);
if (fctx == null)
logger.fatal("FacesContext is null");
ValueBinding bind =
FacesContext.getCurrentInstance().getApplication()
.createValueBinding("#{facadeService}");
if (bind == null)
logger.fatal("ValueBinding is null");
...
}
any advice???
thanks in advance,
Omid
