Hello, I'm having a similar problem. I have classes that are being used by the 'robot', its 'legs' and its 'toes'. I'm using children of the 'robot' Injector for the legs and children of the 'leg' Injectors for the 'toes'. One of these classes uses an injected Injector. Objects created with this injector should have bindings available to get the 'robot', 'leg' or 'toe' in which they exist. Since this class is also used by the 'robot', the Injector seems to use the parent (or grandparent) Injector to create instances for the the child modules and that is the one that ends up getting injected. A quick search for "child injector" in this group turns up a post from last August where Dhanji suggested binding the Injector using a provider. I'm not sure this would work since the 'right leg' doesn't actually know it's the 'right leg' but apparently declaring a binding of an Injector is not legal in the Guice 2.0 jar that is currently in central maven anyway.
Has anyone gotten something like this working?
