OK, I've addressed the verbosity of programmatically starting a new dialog.
The programmatic start and navigate now collapses to:
// Create and start the "CheckOut" dialog
dcontext = manager.create(context, "CheckOut");
dcontext.start(context);
return null;
We should consider pushing the actual navigation on an ongoing DialogContext
instance to inside the advance() method as well, although in practice that
would only simplify a bit of logic inside Dialog2NavigationHandler, not any
application level code.
