org.directwebremoting.extend.FormField
The result of a DWR query is normally a set of name/value pairs unless we are doing file-upload in which case there is more information with each field. This class replaces the value part of the set of name/value pairs to provide access to the extra information. @author Lance Semmens [uklance at gmail dot com] @author Niklas Johansson [niklas dot json at gmail dot com]
