Custom NavigationHandler

[Laurie Harper]

I was just looking at implementing a custom navigation handler. I need 
to basically replace the standard implementation with my own to extend 
the semantics.

I thought I'd start with the MyFaces implementation and just tweak it to 
do what I need. But NavigationHandlerImpl depends on a bunch of other 
MyFaces implementation classes, including ones that represent the 
individual navigation rules/cases.

This leads me to suspect that there's no standard, portable way to 
implement a navigation handler that *replaces* the default one rather 
than just decorating it. Is that true, or are there portable equivalents 
to the implementation APIs that I can use to get at the application's 
navigation rules?
