Hello everybody,

I have a very weird comportment of logstash when I try to collect integers datas from jdbc input.  
All is ok when i collect them alone (only the integers datas) but when i collect the same integers datas with a lot of others fields i have the value 'null' for this integers datas.

Do you have any idea ?

Thanks in advance.

Rod.
