Gary,
Thank you for your help. Some things are not totally clear to me though, so
excuse my ignorance in these matters. When you say:
> The shale-dialog does this sort of thing [2]
Do you mean it already does it in some way like:
<dialog name="go_contactus" start="exit">
<end name="exit" viewId="/#{sessionVars.locale}/contactus.jsf"
redirect="true"/>
</dialog>
Which I tried and it doesn't recognize the the EL and just redirects to the
viewed as a string. The description with your link [3] seems to describe
exactly what I need, but when implemented, it doesn't behave any different
from when I don't use these definitions.
So I guess my question is, do I go and extend
org/apache/myfaces/application/NavigationHandlerImpl.java and build a way to
recognize the EL in my viewId (how would be the next question) or is it a
matter of configuring my faces-config.xml to use the correct handlers that
can already do this?
Thank you for your patience with my coming to grips with the issues at hand,
Joost

You are not using the best extension point. The navigation handler is the
place I'd try adding this extension [1]. The shale-dialog does this sort of
thing [2]. Like the other JSF extension points, you will want to decorate
the original that will be passed via the custom navigation handler's
constructor. The custom navigation handler gets registered in the faces
config [3].
