Hi, The first thing I did was these tests,i made a simple test case that create a Cas with 17 views and then serialize using XmiCasSerializer.serialize(newJCas.getCas(), fis) and serializes correctly. Also i made other test, initialize the same AE but of local way with UIMA API and process the same input documents and the processing is correct and then serialize the CAS, without problem.
The error is with AE deployed in uima-as and consuming it. 2017-02-09 17:30 GMT-05:00, Marshall Schor <m...@schor.com>: > one thing that would help track this down is a small isolated test case. > > Do you think uima-as is needed?
