Hi again,
I solved the problem.
for the intressted reader ;) :
protected FacesContext getFacesContext(HttpServletRequest request,
HttpServletResponse response) {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext == null) {
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;
}
