public class TextDuplicatorHandleRequestImpl extends WContainer
This component demonstrates how to add some simple control logic, by overriding the handleRequest method.
The java code placed in the handleRequest method can look at, and manipulate, the values stored in the various child components.
A word of warning. When using the handleRequest technique, it is important to remember how the request/response sequence is processed. The serviceRequest method performs a depth first collation of all visible components and then calls handleRequest on each component in the list. This means that only child components of the component you are overriding handleRequest on will have had a chance to update themselves for the current request. Don't try accessing data in components higher up in the component tree.
