NavigationHandler registration

[Laurie Harper]

I have a requirement to register a custom NavigationHandler 
implementation at the bottom of the delegation stack, rather than at the 
top as happens when registering through WEB-INF/faces-config.xml. 
Basically, I need to make sure that delegating navigation handlers, such 
as Shale's DialogNavigationHandler, or the equivalent in Trinidad, 
delegate to my nav handler, *not* the other way around. Basically, my 
nav handler needs to replace MyFaces' default implementation, with the 
normal registration of delegating nav handlers from faces-config.xml 
files wrapping that.

I know JSF (at least prior to 1.2, anyway) doesn't provide a mechanism 
to achieve this; does MyFaces? I know I can modify the 
standard-faces-config.xml file bundled in myfaces-impl.jar to get what I 
want (actually, that sets my nav handler up as the first delegating 
handler above MyFaces', but that's 'good enough' for my purposes). What 
i'd like, though, is a config option that would have the same effect.

Alternatively, is there any other mechanism I can use to achieve this, 
MyFaces-specific or otherwise?

Thanks,

L.
