Variables issue in activiti Engine

Question asked by bhujangarao on Aug 19, 2018

Hi Team,we are using Activiti 5.14 version and strong data in external oracle database and having below problem from long back.

Problem: we are creating variables and storing in process context object and àccess those variables in BPMN diagram as per the business requirement. We have around 15 products and each have different BPMN work flow diagrams. So if we change or create any variables are not detecting and throwing null pointer exception after prod release for already flow stared requests. And for new work flow requests it's working .Can some one please help me how to solve this problem in activiti side. Right now we are maintaining 2 code versions to avoid this problem and configuring prod release dates and routing the requests accordingly for old and new requests.
