org.zkoss.zk.ui.Component
An UI component.
There are two kind of life-cycles: one is page creations and the other is asynchronous updates.
The Page Creation

The page creation occurs when a page is about to render at the first time. The detailed phases can be found in the devloper's guide.
The Asynchronous Update

The asynchronous update occurs when users does something on the browser, such as changing the content of input, clicking buttons and so on. Such behaviors are packed as requests, queue in the browser, and then send to the server at the proper time. The detailed phases can be found in the developer's guide.
No Synchronization Required

To simplify the development of components and applications, invocations of methods of components and event listener are all serialized. In other words, application and component developers need not worry synchronization and other thread issues (unless you are developing background thread to handle long operations).
It also implies a limitation that you cannot access components belonging to other desktops when processing an event. @author tomyeh
