A NavigationHandler is passed the outcome string returned by an application action invoked for this application, and will use this (along with related state information) to choose the view to be displayed next.
A default implementation of
NavigationHandler must be provided by the JSF implementation, which will be utilized unless
setNavigationHandler() is called to establish a different one. This default instance will compare the view identifier of the current view, the specified action binding, and the specified outcome against any navigation rules provided in
faces-config.xml file(s). If a navigation case matches, the current view will be changed by a call to
FacesContext.setViewRoot(). Note that a
null outcome value will never match any navigation rule, so it can be used as an indicator that the current view should be redisplayed.
