Class FormField

java.lang.Object
  org.directwebremoting.extend.FormField

public class FormField
extends java.lang.Object

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.
