Serializable object not being persisted.

created by Phillip Thurmond in jBPM - View the full discussion

I have a class OrderType which is serializable, but I'm getting the following exception when I execute my process. From my understanding of the documentation, any object which is serializable can be persisted by jbpm. Is there any configuration necessary to enable this? If not, any ideas of potential causes?
