public class Init
extends BaseInit

Init is a JSF component implementation for initial of page

Once this is specified, an instance inside this tag is created and Initiator.doInit(org.zkoss.zk.ui.Page, java.lang.Object[]) is called before the page is evaluated. Then, Initiator.doAfterCompose(org.zkoss.zk.ui.Page) is called after all components are created, and before any event is processed. In additions, Initiator.doFinally() is called after the page has been evaluated. If an exception occurs, Initiator.doCatch(java.lang.Throwable) is called.

A typical usage: starting a transaction in doInit, rolling back it in Initiator.doCatch(java.lang.Throwable) and commit it in Initiator.doFinally() (if Initiator.doCatch(java.lang.Throwable) is not called).

Usage:

 <z:init useClass="my.Init" arg0="hello"/>
 

This component should be declared nested under Page.
