The actionListener Attribute

       <h:commandButton image="mountrushmore.jpg"
          actionListener="#{rushmore.handleMouseClick}"
          action="#{rushmore.navigate}" ... />

The handleMouseClick method:

• Since it is a listener, it is passed the action event containing click information.

• It cannot affect navigation, so it stores an outcome string in an instance field.

The navigate method:

• Is called after the listener method.

• Simply returns the stored outcome string.
