[jbpm-issues] [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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
