FWIW, in this particular instance, it looks like you wouldn't even need to provide the Provider binding, because of the fact that it's using child injectors. With the prior version of the code, which didn't create a child injector, you would need to wrap up your own child injector that bound things explicitly. With the version of AssistedInject, when your AImpl is constructed, it's using an internal child injector that already has A bound to your AImpl the assistedinject factory created.
So, so long as this is actually your problem (and it's not just a simpler example for the sake of email), it looks like AssistedInject2 is actually saving you code. :-) Sam On Tue, Jun 9, 2009 at 8:34 PM, [email protected] <[email protected]> wrote: > > > > On Jun 9, 8:40 am, Dmitry Skavish <[email protected]> wrote: > > 1) A binding to guice.test2.A was already configured at > > guice.test2.AFactory.create(). > > Gotcha.
