Ok, I think I know what I was doing wrong. I never added the child
injector to my app. I thought the child injector was contained in the
parent injector, but after looking at some of the Guice tests I realized
you could create more than one Injector instance, a parent and children
and children of children and so on.
I did this:
Injector parentInjector = Guice.createInjector(getModule1());
injector.createChildInjector(getModule2());
thinking all I needed was parentInjector when I should of done this.
Injector parentInjector = Guice.createInjector(getModule1());
Injector childInjector = injector.createChildInjector(getModule2());
Let me know if I have missed any thing else.
Thanks,
Warren Bell
