The only way to make that "clean" is to push the translation effort
into your ActionForm and nest your real beans in the ActionForm. you
would then have a String value that you convert and set into your
nested bean. The other option is to write a different BeanUtils
Converter implementation for numerics and register it
(http://jakarta.apache.org/commons/beanutils/api/org/apache/commons/beanutils/ConvertUtils.html#register(org.apache.commons.beanutils.Converter,%20java.lang.Class).
I would personally avoid cluttering up your domain bean with faux
setters and getters.
