Alyien operator output problems

Hi everyone,

I'm trying to use Aylien Sentiment operator and everything seems fine (it works correctly) until I try to connect the output to another operator. I always get an error message:

And the attribute list of the aggregate operator (in this case) is empty. Same problems with any operator that needs to read the example set from the Aylien operator.

Any ideas what might be wrong?

Thanks.
