Examples of org.apache.tapestry.util.ComponentAddress

org.apache.tapestry.util.ComponentAddress
The ComponentAddress class contains the path to a component, allowing it to locate an instance of that component in a different {@link org.apache.tapestry.IRequestCycle}.
This class needs to be used mostly when working with components accessed via the {@link org.apache.tapestry.IRender} interface. It allows those components to serialize and pass as a service parameter information about what component they have to talk to if control returns back to them.
This situation often occurs when the component used via IRender contains Direct or Action links. @version $Id: ComponentAddress.java 243791 2004-02-19 17:38:13Z hlship $ @author mindbridge @since 2.2
