Well, I tried something too complicated ... I have no need to use a swimlane, but just pooled actors on my task. So I defined my task node this way : <task-node name="validation"> | <task> | <assignment pooled-actors="#{assignmentHandler.assignByRole('USAGE')}"></assignment> | </task> | <transition to="acceptation" name="ok"></transition> | <transition to="refus" name="nok"></transition> | </task-node> And it works well, datas in JBPM tables look OK. Nevertheless when I use the taskInstanceList built-in component in my facelet, it returns an empty list. Any idea why ?
