Thank you Thomas,

that's what I was thinking -- and I'm playing with a custom code
generator already :)

Just wondering what "they" mean with the GIN comments in the doc/code...

In my pre-2.1 homegrown framework I use a code-generated presenter
config based on a Ginjector (declaring all the getFooPresenter()
methods annotated with location (place) and security informations). My
presenters were singletons and were "started" with the actual Place.
That way I could use GIN to (constructor) inject all my dependencies.
I'm not sure if I like this 2.1-design (constructing activities with
the actual place) which means I cannot use GIN to construct them.
Maybe I make my activities extends some AbstractBaseActivity
containing a setPlace(P place) method which is called in the
ActivityMapper...

Sebastian
