My hunch is that "dialog:" is not actually really launching
the dialog. As for why, I'd wonder how Spring Web Flow
is installing. My guess is that it's a NavigationHandler
wrapper (is that accurate?) and if so, for "dialog:" to magically
work you'd have to make sure that the Trinidad "dialog:"
ViewHandler wrapper wraps the SWF ViewHandler wrapper,
not the other way around.
