But then how do you plan to write a converter to convert a String[] to a
SettingList? Also why is aggregation a bad design?

That's ok but your SettingList is not full List implementation and you
have to specified how to convert array to SettingList that's why you

This tells Xwork which converter to call if it will need to convert

convertion mechanism, did you setup xwork-conversion.properties file
as mentioned in documentation [1]?
