All Implemented Interfaces:

Serializable, Control, Container, Stateful

public class NestedCayenneForm
extends org.apache.click.extras.cayenne.CayenneForm

Provides a CayenneForm which uses a Nested DataContext that is created as a child of the DataContext bound to the current Thread.

Using a nested DataContext allows the form to keep its state across multiple requests even if org.apache.click.extras.cayenne.DataContextFilter is configured to rollback changes after each request, which is the case for click-examples.
