[jboss-user] [JBoss jBPM] - De-Persistence problem with Node?

I'm using jBPM 3.1.4, Weblogic 8.1, Hibernate 3.2.2.
I stored the following test process definition:
| <process-definition name='"joe"'>
| <start-state name='start'>
| <transition to='s' />
| </start-state>
| <task-node name='myTaskNode'>
| <transition to='end' />
| </task-node>
| <end-state name='end' />
| </process-definition>
|
Then created an instance, and signaled() it once.
I then (later, in a different jbpmContext) do the following:
| ProcessInstance pi = context.loadProcessInstance(215);
|
| Token tok = pi.getRootToken();
|
| Node n = tok.getNode();
|
|
| System.out.println(n.getName());
| System.out.println(n.toString());
| System.out.println(n.getClass().getName());
|
| TaskNode n = (TaskNode)t2.getNode();
|
The output of the three System.out.println()s is:
| myTaskNode
| TaskNode(myTaskNode)
| org.jbpm.graph.def.Node$$EnhancerByCGLIB$$92204161
|
Which is immediately followed by:
java.lang.ClassCastException
Which is obviously because the class "org.jbpm.graph.def.Node$$EnhancerByCGLIB$$92204161" cannot be cast to a TaskNode.
But how come the task knows it's a tasknode but isn't? I say it knows it is a task node, because it's toString() method returns "TaskNode(myTaskNode)".
