[jboss-user] [JBoss jBPM] - NPE from ProcessState

[brosnt]

I have a simple example usage of the ProcessState node, where a parent process contains a reference to a child process via a ProcessState node. The process definitions are stored in a relational database.

The child process actually executes successfully (I have a single node with an ActionHandler that prints the node name to System.out).
However, I receive a NullPointerException in the ProcessState.leave() method - the executionContext.getSubProcessInstance() method call (first line in the method) returns null, and the next line then attempts to invoke a method on this null reference.

I see from the debugger that the executionContext object in the ProcessState.execute() method is different from the executionObject I later see in the ProcessState.leave() method - though in both methods the subProcessInstance member of the executionContext object is null.

Here are my two process definitions:

<process-definition
  xmlns=""  name="parent">
   <start-state name="start">
      
   </start-state>
   <end-state name="end1"></end-state>
   <process-state name="process1">
   	  <sub-process name="child"/>
                  
   </process-state>
</process-definition>


<process-definition
  xmlns=""  name="child">
   <start-state name="start">
      
   </start-state>
   <end-state name="end1"></end-state>
   
   	<action name="action" config-type="bean" class="SysoutActionHandler">
		
      
   
</process-definition>

Any ideas? Given my limited analysis of the ProcessState.java code and related classes, I do not see how this can actually work - am I seeing a bug?

Thanks
