I'd also suggest posting what '#{country.selectedCountry}' points to. Its not in the class. If this doesn't exist, its possible that JSF is getting upset because it wants to convert the type of the SelectItem, but doesn't really have a target type, so it fails or whatever.
Regardless you need that value available.
