Hi friends: The jbpm doc say that I need have to invoke "Token.signal " for the process run.But I study the websale example and I find that this example don't invoke Token.signal anywhere. Why it don't invoke the Token.signal method ,the instance could process normally ? Does the "jbpmContext.save(taskInstance)" equals "Token.signal()" ? Thks!
