[jbpm-issues] [JBoss JIRA] Updated: (JBPM-1164) Null Pointer Exception is thrown when subprocess is leave event is fired.

Null Pointer Exception is thrown when subprocess is leave event is fired. ------------------------------------------------------------------------- Key: JBPM-1164 URL: https://jira.jboss.org/jira/browse/JBPM-1164 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.2.2 Environment: Windows XP Pro, Sun JDK 1.5.0_13 Reporter: Gurpreet Sahota Assignee: Thomas Diesler Fix For: jBPM 3.3.2 GA I have a process flow where process (A) calls a process state that in turn calls subprocess (B). When Subprocess "end" state is signalled then I receive a Null Pointer Exception. Following is stack trace 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) When debugging, it turns out that "leave" method in ProcessState tries to retrieve subProcessInstance from execution context. This is set to null causing exception. If executionContext.getToken() is used to retrieve the subProcessInstance, then it is not null.
