Hi,
That’s the point - you do not need to store the number of days since creation, you calculate it: Today-Customer.ActivationDay. Other parameters are also persisted in your data model, e.g. update Customer set Customer .status=“No Mail” where Customer.ID=? etc. Why would you use jBPM persistence to store the values which belong to YOUR business logic? jBPM is about to help you solving other problems. I’m not saying that there is no use of it in your project, but what you have described above in not for jBPM implementation in my opinion. That’s all I’m trying to say.
Thanks,
Vladimir
