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

       private void kickOffProcess(String processname, String [] attrnames, java.io.Serializable[] attrvalues) {
 org.jbpm.JbpmConfiguration jbpmConfiguration = org.jbpm.JbpmConfiguration.parseXmlString(
 "<jbpm-configuration>" +

 // engine from the services that jbpm uses from
 // the environment.

 );
 org.jbpm.JbpmContext jbpmcontext =jbpmConfiguration.createJbpmContext();

 try {

 org.jbpm.graph.exe.ProcessInstance pi = jbpmcontext.newProcessInstance(processname);

 for (int i=0;i<attrnames.length;i++) pi.getContextInstance().setVariable(attrnames,attrvalues);

 pi.getRootToken().signal();

 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?
