I would like to get all the users that participated in a given process instance.
The following code:
List<HistoryTask> history = historyService.createHistoryTaskQuery().executionId(processInstance.getId()).list();
System.out.println("----------");
for (HistoryTask e : history) {
System.out.println(e.getAssignee());
}
System.out.println("----------");
Has a limitation for my needs. Imagine that I have a process with one task task1. task1 is assigned to user a. User a delegates task1 to user b, and then b delegates task1 to user c. The above code will only show user c while I would like to receive all the users [a, b, c].
What is the best way to achieve this requirement? If you could provide some processes + source code fragments it would be great.
