Hi Mario,
I thought SelectItem/converter is always used in conjunction with an input
component? Using it in conjunction with SelectOneMenu, SelectOneRadio etc
would not require this test. The following would be good enough:
public String getAsString(FacesContext context, UIComponent component,
Object value) {
if (value == null) return "";
Enum e = (Enum) value;
return e.getClass().getName() + "@" + e.ordinal();
}
Where else could the converter be used? Sorry if this is JSF 101.
Cheers,
Yee

The idea behind this converter is, that in case of an input component
the conversion has to be reversible (or symmetric), thus, the
[EMAIL PROTECTED] rendering, in any other case - usually output components
only - it uses enum.toString() to have a nice user-readable
representation (assumed that toString() has been overloaded)
Ciao,
