[jboss-user] [JBoss jBPM] - how to signal a sub-process in 3.2.2

hello. do i need to explicitly signal sub-process? like... processInstance.getRootToken().getSubProcessInstance().signal() if i signal the parent process it throws a null point exception upon leaving the process-state that contains the sub-process. java.lang.NullPointerException at org.jbpm.graph.node.ProcessState.leave(ProcessState.java:204) at org.jbpm.graph.exe.Token.signal(Token.java:195) at org.jbpm.graph.exe.Token.signal(Token.java:140) at org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:271) thanks. david f.
