Subject Re: Discard already sent asynchronously CASes to UIMA AS pipeline
Date Tue, 19 Mar 2013 08:26:06 GMT
Hello!
  Thank you for the response. My remote service has an
AgrregateAnalyssEngine that handles (remote and also co-located) NON CAS
Multiplier AnalysisEngine.

Thanks you very much and I look forward for fix.
Regards,
  Florin
