Listener:
org.zkoss.zk.ui.util.Initiator
[since 5.0.7]
A listener could implement Initiator to handle the initialization of a ZUML page, as if it is specified in the init directive. This kind of listeners is called system-level initiators.
Each time a ZK page is created, ZK will instantiate one instance for each registered system-level initiator and the invoke Initiator.doInit(Page, Map) and other methods.
If you want to process only certain pages, you can check the request path by calling Desktop.getRequestPath() (the desktop instance can be found thru the give component).
Since an individual instance will be instantiated for each page, the implementation needs not to be thread safe.
