All Implemented Interfaces:

DocumentGenerator, ResourceConsumer, java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class AutoForm

extends TableWrapperForm

a form constructed by reading the servlets and widgets it requires from a database. Not yet finished, not yet stable, use at your own risk.

Version:

$Revision: 1.4.4.1 $ This revision: $Author: simon $

  $Log: AutoForm.java,v $
  Revision 1.4.4.1  2005/12/23 10:48:33  simon
  Brute force tidy up after CVS server crash: this time it should work.

  Revision 1.4  2004/05/05 15:09:19  simon
  bugfix: in recent changes in Form.handleAction() (revision 1.78 of Form), if there was no prior widget set
  the default action handler did NOT get called. Fixed, but this is such a critical bit of logic that any new bugs
  are likely to be in this area.

  Revision 1.3  2003/08/20 09:38:35  simon
  Code cleanup with eclipse; mostly removal of exccessive includes

  Revision 1.2  2002/03/18 10:02:38  simon
  Checkin for 1.6.6; replacement of ContextElement (now deprecated) with
  ContextElementGenerator.

  Revision 1.1  2001/05/03 14:52:53  simon
  Moved phoenix/AutoServlet to htform/AutoForm, because it depends on
  no-args constructurs for Widgets which I did not want to make
  public. Changes to widgets to support this, namely by adding protected
  no-args constructors. This functionality is not really yet ready for
  prime time and may change before becoming truely stable.
