Subject Re: Injecting nested resources using UIMA fit
Date Fri, 22 May 2015 15:04:36 GMT
I am not sure that I have ever tested nested resources on readers;
certainly, I have never tested them on flow controllers - only on AEs.

Anyway - are you using the uimaFIT base-classes for readers and flow
controllers - those that call ExternalResourceInitializer.initialize(...)
in their initialize(...) methods?

Can you provide some example code?

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.
