Minor Description
org.apache.wicket.markup.html.form.EnumChoiceRenderer#getDisplayValue() adds unnecessary indirection by providing overrideable #postprocess() method.
If an application doesn't want to use the default implementation to resolve a display value by using i18n resources then it should provide its own custom implementation of IChoiceRenderer because org.apache.wicket.markup.html.form.EnumChoiceRenderer#getDisplayValue is final and it will throw MissingResourceException.
If an application needs to use different logic it should be able to override #getDisplayValue(). If it needs to do something like #postprocess() then it can do:
public Object getDisplayValue() {
Object orig = super.getDisplayValue();
return manipulate(orig);
}
