Hi Jerwah, Good work. I cannot understand what the class is doing cos I am new to this project, but it is passing my testcase and joining all parents, and this is great. One comment, the line: executionContext.getJbpmContext().save(executionContext.getProcessInstance()); was throwing a null pointer exception in my test cases, so I commented it out. In the test cases I am not using persistency, just testing the navigation. But shouldn't the persistency be out of the code for the join?
