---------------------------------------------------

                 Key: JBPM-895
                 URL: http://jira.jboss.com/jira/browse/JBPM-895
             Project: JBoss jBPM
          Issue Type: Bug
          Components: BPEL
    Affects Versions: jBPM 3.1.3
            Reporter: Tom Nguyen
         Assigned To: Tom Baeyens


I have a problem with my process composition
Exception happen when deploying process with sub process:

public void deployProcessDefinition() {
ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("main/processdefinition.xml");
ProcessInstance instance = new ProcessInstance(processDefinition);
JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
try {
jbpmContext.deployProcessDefinition(processDefinition);

} finally {
jbpmContext.close();
}
}


java.lang.NullPointerException: can't create a process instance when processDefinition is null
	at org.jbpm.graph.exe.ProcessInstance.<init>(ProcessInstance.java:87)
	at org.jbpm.graph.exe.Token.createSubProcessInstance(Token.java:571)
	at org.jbpm.graph.node.ProcessState.execute(ProcessState.java:109)
	at org.jbpm.graph.def.Node.enter(Node.java:316)

<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="urn:jbpm.org:jpdl-3.1" name="main">
<start-state name="start">
</start-state>
<end-state name="end"></end-state>
<process-state name="sub">
<sub-process name="sub"/>
</process-state>
</process-definition>

This is my sub process:

<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="urn:jbpm.org:jpdl-3.1" name="sub">
<start-state name="start">
</start-state>
<end-state name="end"></end-state>
</process-definition>
