I tried to implement the filter from the following resource (but I only did

http://marcchung.com/2005/01/24/performing-a-jsf-get-2/
http://marcchung.com/2005/01/24/performing-a-jsf-get-2/
But looking at the stacktrace below can you tell me why
FacesContext.getCurrentInstance() returns null inside my backing bean?
