Perhaps I'm not looking in the right places, but I have not seen any examples/tutorials that clearly explain what I'm striving to do.
I have deployed an application that runs a simple process consisting of the start node, two service task nodes, and the end node. The application is persistent and I'm using a StatefulKnowledgeSession. Here are the things I'd like to know:
- If the process fails before completion, how do I abort the current workitem and STOP the process from completing? I don't want the next service task to execute until the first is successfully completed. Currently, when I encounter an exception, which would crash the program when not running in a persistence context, I return a failure code to the workitem handler and invoke abortWorkItem(), the process proceeds to the next node. I've seen one suggestion to use a wait state. WHERE? HOW
- Explanation of status codes and states, and how they can/should be used to rehydrate a process
