I think so. I don't want the converter to run on an empty field either.

I also think it would be nice to have these ValidationResultMap methods:

String getOriginalValue(name): Should only return null if name doesn't
exist.
Object getConvertedValue(name): Can return null.
Object getConvertedOrOriginalValue(name): Return the original value if
invalid--otherwise the converted one.
String [] getGroupErrorMessages()
String getErrorOrMessage(name): Return the message if valid--otherwise the
error msg.

Instead of having to deal with two ValidationResultMaps, it would be nice to
have a wrapper object.
