Class FieldErrorView

java.lang.Object
  org.nakedobjects.plugins.dnd.viewer.view.simple.AbstractView
      org.nakedobjects.plugins.dnd.viewer.view.simple.FieldErrorView

All Implemented Interfaces:

java.lang.Cloneable, View

public class FieldErrorView
extends AbstractView

Displays an error message in place of a normal field when a problem occurs, usually due to a programming error, and the normal field cannot be created. A example of this is where value field is declared in a naked object, but the programmer forgot to instantiate the value object, causing null to be returned instead, which is an illegal value.
