public class Button
extends BaseCommand

Button is a JSF component implementation for Button, This component should be declared nested under Page. This class also implements ActionSource. That means you can use action and actionListener features on this component.
To use those features, you must declare a namespace of "http://java.sun.com/jsf/core" with a prefix (say 'f' in below example), add attribute of those feature with this namespace (for example f:required="true")in you jsf page. For more detail of ActionSource features of JSF, you can refer to http://java.sun.com/products/jsp/

Example of action :

 <z:button id="btn" label="submit" f:action="#{CommandBean.actionPerform}"/>
 

Example of actionListener :

 <z:button id="btn" label="submit" f:actionListener="#{CommandBean.onActionPerform}"/>
 

In some application server which doesn't support attribute namespace you can use attribute prefix 'f_' to replace attribute namespace
For example,

 <z:button f_action="#{CommandBean.actionPerform}"/>
 

To know more ZK component features you can refer to http://www.zkoss.org/
