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/downloadImage/2-827948-21137/450-194/testeV2.png
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:
