The org.zkoss.zk.ui.util.ExecutionInit interface

Listener:

org.zkoss.zk.ui.util.ExecutionInit interface

A listener could implement ExecutionInit to initialize a new execution.

When ZK Loader and Update Engine created a new execution, it invokes the init method of this interface such that developers could plug the application-specific codes to initialize an execution.

Tip: Executions might be stacked. To know whether it is the first execution since a (Servlet) request is processed, you can check whether the parent argument is null.

A developer can prevent an execution from being created by throwing an exception in the init method.
