[JBoss JIRA] Created: (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: http://jira.jboss.com/jira/browse/JBPM-1164
Project: JBoss jBPM
Issue Type: Bug
Affects Versions: jBPM jPDL 3.2.2
Environment: Windows XP Pro, Sun JDK 1.5.0_13
Reporter: Gurpreet Sahota
Assigned To: Tom Baeyens
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.

[JBoss JIRA] Created: (JBPM-1147) iCalendar Wrapper for jBPM tasks
