Hi Hong,

We have a PhaseListener that handles authentication. The PhaseListener
retrieves an instance of NavigationHandler via

NavigationHandler navigationHandler = facesContext.getApplication().getNavigationHandler();

next it calls a navigation rule like this

navigationHandler.handleNavigation(facesContext, "", "notAllowed");

which works on GF2. It doesn't on GF3 and it throws an NPE. The
corresponding navigation rule in faces-context.xml is

    <navigation-rule>
        <navigation-case>
            <from-outcome>notAllowed</from-outcome>
            <to-view-id>/notallowed.xhtml</to-view-id>
            <redirect/>
        </navigation-case>
    </navigation-rule>

Any thoughts?


Thanks, Wouter
