thanxs for your quick answer. Now i'm only using task, but i don't know what could happen tomorrow. I want to think that my process could be a group of task , nodes, or whatever. Look, i´m building a tier who comunicate with jbpm. So i want to call a signal method to my tier and this method calls a signal to jbpm. i'm not clear enough , not? really thanxs.
