Re: Shale and Trinidad
I can see that the shale filtered and viewhandler are triggered.. all
seems configured correctly, but the view controller isn't working.
Can you explain a little how it is supposed to work? Where are the
requests intercepted and those callback methods called? I see those
some code in your PhaseListener that create a ViewControllerCallbacks
instance, but I can't find where its metodhs are invoked. If I knew
it, maybe I could find where the problem is..
Thank you

I was trying with the init() method but it was never called.. I'm now
trying with prerender() and it works.

The actual event calls (via ViewControllerCallbacks) happen in
ViewPhaseListener .. the call to preprocess is triggered at the end of
Restore View phase, and the call to prerender is triggered at the beginning
of of Render Response phase.
Does the managed bean name of your backing bean match the required naming
pattern to be recognized as a ViewController? The precise rules are listed
in the javadocs of "org.apache.shale.view.impl.DefaultViewControllerMapper".
