JavaServer Faces

Name

UICommand

Synopsis

This class represents a command component. A command component lets the user issue a command to the application, either to adjust the view or initiate backend processing. It’s often rendered as button or a link, and it must be a child component of a form component, directly or indirectly. The default rendererType is javax.faces.Button.

When triggered by a user, the command component fires an ActionEvent, which can be handled by the application through an action method or one or more listeners, in the order: javax.faces.event.ActionListener instances (in the order they are registered), the action listener method, and then the action method.
