heyi, As Far As I Know (AFAIK) jBPM does not do any kind of checks while signaling a token on whether the person who has been assined is signalling. The way this is controlled in the sample web-app is by showing only my tasks to me on login so that i can signal or act on only my tasks. In other words this should be controlled by access to particular task by UI or other means rather than by the signal command. Hope it helps.. cheers!
