You cannot cache the FacesContext. The FacesContext is created and destroyed for each HTTP request. For non-JSF requests, such as requests to Servlets, the FacesContext does not exist at all.

Also, HomeBean is the name of the class The proper capitalization of the instance of that bean is "homeBean".


Customer surveys are for companies who didn't pay proper attention to begin with.
