Hello:
Tom, Roland, Koen, I hope you jBPM guys can help me (anybody else's help is
apreciated too, but as this seems to be a jBPM API problem...)
Tools:
JBoss 4.0.4GA, jBPM 3.1.2, jBPM DB is running on MySQL 5.0, JDK 1.5.08.
I'm having an exception while instancing a process.
Here is the error:

This is my process definition:

| <transition name="" to="end1"></transition>
| </task-node>
| <end-state name="end1"></end-state>
| </process-definition>
|
And finally, here is the line where I'm getting the exception...
| ProcessInstance processInstance =
jbpmContext.newProcessInstance("proceso_perfil_proveedor");

It looks OK to me, but as soon as the values retrieved try to be assigned to a
ProcessDefinition-type variable, I got the "ClassCastException".
I've been dealing with this problem for about a week, so any help would be
mostly apreciated.
It seems to be an error while executing the next query:
Thanks in advance.
