Hi all, I am running a SimplePipeline which consists of a Reader and two Aggregate Analysis Engines. The output CAS of the first AAE is meant to feed into the second AAE. However, I find that even though the output of the first AAE is correct, it is different from the input to the second AAE. I have verified this by writing to XMI as the last step of AAE 1 and the first step of AAE 2. In AAE 1 I have a CAS merger as the final step and a flow controller which is set to drop the input CAS to the merger. This is working fine: Only the merged CAS remains after the merge step. And yet, the input CAS to AAE 2 is missing the annotations which were added by annotator steps in AAE 1 before the merge.
If I combine both AAEs into one super-AAE and add this one to the SimplePipeline instead, it works fine. So, there is a work-around. I am just curious why the AAEs might behave this way when I have the separate. Thanks a lot. Cheers, Martin
