[jboss-user] [JBoss jBPM] - JBPMContext.close cause Exception

[NiB]

Hi,
I am using jBPM 3.2 Alpha 2 and trying to start the a process from an ejb3 messagedrivenbean by:

  | 	
  | 		try {

  | 		org.jbpm.graph.exe.ProcessInstance pi = jbpmcontext.newProcessInstance(processname); 
  | 		
  | 		for (int i=0;i<attrnames.length;i++)			pi.getContextInstance().setVariable(attrnames,attrvalues);	
  |

  | 
  | 		jbpmcontext.save(pi);
  | 		} catch (Exception ex) { 
  | 			ex.printStackTrace();
  | 		} finally {
  |                        // EXCEPTION HERE
  | 			jbpmcontext.close(); 
  | 		}
  | 	
  | 		
  | 	}

I get an exception when I am calling jbpmcontext.close():

The task nodes in the process appears in the webapp, but when I use
a transition button they won't follow the transition. Can anyone help me?
