[jboss-user] [JBoss jBPM] - classcast exception getting tasknode

[AJanz]

i've written my own command to create tasks at runtime.

but when i try to get the tasknode i got an class cast exception

2008-10-20 17:26:23,496 INFO  [STDOUT] node name:in Bearbeitung
2008-10-20 17:26:23,496 INFO  [STDOUT] node class:class org.jbpm.graph.def.Node_$$_javassist_80
2008-10-20 17:26:23,496 ERROR [STDERR] java.lang.ClassCastException: org.jbpm.graph.def.Node_$$_javassist_80 cannot be cast to org.jbpm.graph.node.TaskNode

although it is really a tasknode...

what am i doing wrong?

here is the code


							ProcessInstance pi = jbpmContext.getProcessInstance(processid);
  | 							
  | 							if (cat.isDebugEnabled()) {
  | 								cat.debug("add task command");
  | 								cat.debug("token:"+ pi.getRootToken().getId());
  | 								cat.debug("node name:"+ pi.getRootToken().getNode().getName());
  | 								cat.debug("node class:"+ pi.getRootToken().getNode().getClass());
  | 							}
  | 							TaskNode tn = (TaskNode) pi.getRootToken().getNode();
  | 							Task t= tn.getTask("mytask");
  |
