30 | * This class is used as a double wrapper for NavigationHandler | |
31 | * and ConfigurableNavigationHandler to be backwards compatible | |
32 | * to the pre JSF 2.0 NavigationHandlers which are not | |
33 | * ConfigurableNavigationHandlers (since JSF 2.0 the standard | |
34 | * NavigationHandler implementation has to inherit from | |
35 | * ConfigurableNavigationHandler). | |
36 | * | |
37 | * It just passes through handleNavigation() to the wrapped | |
38 | * NavigationHandler and getNavigationCase() and getNavigationCases() | |
39 | * to the wrapped ConfigurableNavigationHandler. | |
