suppose a simplest process A -> B -> C -> D. if now the process is on node C, how to let the process back to B without creating a new transition from C to B ? what's more, if the process starter(who started A) wants to cancel his application before C is operated. how to realize this function ? looking forward to reply, this is urgent ! thanks!
