spaceScope java.util.Map A map of attributes defined in the ID space containing this component.
pageScope java.util.Map A map of attributes defined in the page. It is the same as the getAttributes method in the Page interface.
desktopScope java.util.Map A map of attributes defined in the desktop. It is the same as the getAttributes method in the Desktop interface.

Notice that arg is available only when creating the components for the included page (the first argument of createComponents). On the other hand, all events, including onCreate, are processed later. Thus, if you want to access arg in the onCreate's listener, use the getArg method of the org.zkoss.zk.ui.event.CreateEvent class.

forEachStatus ForEachStatus The status of an iteration. ZK exposes the information relative to the iteration taking place when evaluating the iterative element.
