Hi All,
I have tried debugging this for a few hours, and for the life of me I can't
figure out what's going wrong. I know how to workaround it, but I don't
understand why its happening, which has me scared that it may happen in
other places.
The scenario is: We create a parent injector for the core and a child
injector for the UI. The child injector has an odd set of injectable
objects that have the following dependencies: A requires B requires C
requires D requires Provider<A>. All of them are singletons. D does not
call Provider<A>.get() in the constructor. If I change the child injector's
module to have an explicit bind of A, B, C or D then the problem goes away.
I don't understand why that's necessary though -- D should be visible to
child injectors even it was a jit-binding added to the parent (through use
in a child). Neither A, B or C are required by anything else. D is
required by one other class (E), but if I explicitly bind E the problem
still exists.
I'm very willing to debug more... but I could use some guidance on where to
look. I've tried reproducing the problem in a smaller testcase that plays
this exact scenario out, but it won't reproduce (even though this happens
100% of the time on our code).
This is the particular exception:
