What I want to do is that when I come to a task, I’d like to add a task before or after my task.
When the application is a stand-alone one, I may change the process definiton dynamicly by adding UserTasks and SequenceFlows, using
runtimeService.createChangeActivityStateBuilder API. It works well.
But when I came to a distributed application, the problem became more difficult. In this issue, I can not get the change on another server.
I’ve made some attempts as follow.
When the issue comes, I copy and deploy a new process definition and change flow nodes, sequence flows on the new definition, witch will be durable in the db. So even on another server I will gain the changes.
But when I use the
runtimeService.createChangeActivityStateBuilder API to migarate task from one to another. The engine tells me Cannot find activity * in process definition. I think it is because execution still use the old process definition.
May I change process definition the execution uses at runtime? Or Is there any solution may help me.
Thanks a lot.
