Subject Re: Injecting nested resources using UIMA fit

Mario, it appears as if the attachment didn't make it through. No idea
if the list filters it. I expect the code snippet is not too long,
so maybe you can paste it directly to the mail?

I have followed the approach described in the section “Resources implementing SharedResourceObject”.
I just have a resource B that uses resource A and a collection reader and a flow control that
use both A and B but I get "mandatory resource A not set on resource B” illegal state exception.
I use the @ExternalResource annotations to get them injected and I used ExternalResourceFactory.bindExternalResource
with A and B on the collection reader and flow control descriptions when creating my aggregate.
It works if B is not dependent on A but as soon I add the dependency then it breaks. I also
tried to explicitly use ExternalResourceFactory.bindExternalResource on A to B but that caused
null pointer exception in ExternalResourceFactory when trying to bind to the collection reader
right after.
