Navigation Between Pages

• faces-config.xml contains a navigation rule that maps outcome strings to pages:

  <faces-config>
     <navigation-rule>
        <navigation-case>
           <from-outcome>available</from-outcome>
           <to-view-id>/next.jsp</to-view-id>
        </navigation-case>
        <navigation-case>
           <from-outcome>unavailable</from-outcome>
           <to-view-id>/error.jsp</to-view-id>
        </navigation-case>
        <navigation-case>
           <from-outcome>back</from-outcome>
           <to-view-id>/index.jsp</to-view-id>
        </navigation-case>
     </navigation-rule>
     . . .
  </faces-config>

• Current page is redisplayed when
  • The button has no action attribute, or
  • The action outcome is not listed in the navigation rules
