Hi Jim,

I tried your code, and it is not causing any error with the corpus I have. Even using an empty
TrainingParameters.

Maybe it is something related to your training data.

If you like adventures you should try to debug the code and check where exactly is the problem.

> TokenNameFinderCrossValidator works fine if passed null or any other listener except
a "NameEvaluationErrorListener", for  the l"listeners" parameter (last vararglist parameter
in the constructor)...I have tested it with DetailedFMeasureListener and null and it works
fine. When trying to pass an array with the 2 listeners i want (DetailedFMeasureListener,
NameEvaluationErrorListener) it just hangs after the processing the last partition of data,
rather than showing the F-score! It is not a show stopper because i can simply pass null and
get my F-score, but it would be nice if could see the misclassifications as well...
