I haven't found a way to achieve this using the HistoyTaskQuery. I would like to retrieve the task where the transition originates from. | HistoryTask task = HistoryService.createHistoryTaskQuery().executionId(execution.getId()).unique | worked fine for me as long as I just had one task in the process definition. Am I missing anything or is this really as tricky as it seems to be to retrieve the previous task? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4263863#...
