Instead of overriding toString() in your enum, I'd suggest renaming the
method to getLabel().
Then when constructing the SelectItem instances you would do: new
SelectItem(enum, enum.getLabel());
This way the EnumConverter still does its thing when converting between
the view and model and you
get the desired label.
