Hi Andres, I think there is an issue with the json parser. We are using com.jayway.jsonpath as our json parser for CEP. I think there is a known issue for Long type when converting, Please see the link [1].. We also using version 0.8.1 com.jayway.jsonpath. We'll go through this further to find a possible solution and fix it.. Thanks for reporting..
