I am using spring boot with activiti. I have created a simple workflow which is having a single service task ans assigned a java class to this service class. I have one JpaRepository which I am autowiring it in this delegate class. When I start the process, then I am getting NullPointerException on this repository. I think, its not able to get initialized in JavaDelegate class. But I did the same thing in my other service classes and controller classes too and its getting initialized properly. So, is there any way to solve this issue?
