I'm not sure giving the Tapestry engine the power to guess what objects needs
injecting is a good idea. What if you specified one of the properties you
specified below, but wanted to set it manually from pageBeginRender? Or
inject a ServletContext or WebRequest from a different service location?
I think that the little effort it takes to clearly define exactly what gets
injected, and avoid potential ambiguities, overrides any need for automagical
dependecy injection.
