Not really. StringConverter's javadoc says that it takes a String and
makes it a String. The implementation probably just calls .toString() on
the Object, which isn't really what would be wanted.
[quick peek shows:
if (value == null) {
return ((String) null);
} else {
return (value.toString());
}
]
I'd want a getFormatted() method on BeanUtils which uses a FormatUtils to
handle Object->String in the same way ConvertUtils handles String->Object.
