Zeca9 ... [https://community.jboss.org/people/zeca9] created the discussion "Re: JBPM 5.4 - boundary signal event to abort reusable subprocess stopped in a Human Task" To view the discussion, visit: https://community.jboss.org/message/827948#827948 -------------------------------------------------------------- Tks for your reply Maciej. Before do what you told, I tried another approach. I dropped down the boundary events and try to implement this way: https://community.jboss.org/servlet/JiveServlet/showImage/2-827948-21137/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-827948-21... I have another process to call this has reusable subprocess. If the timer event 'Prazo' expires, then the Human Task is canceled and everything runs as expected. But if I signal the event 'Cancelar' before timer event 'Prazo' expires, I get the same error: +1    15/07 11:13:57,756[main] ERROR drools.persistence.SingleSessionCommandService.rollbackTransaction
