I am responsible for an application where the hibernate objects are stored in the jbpm tables. I changed a hibernate object and now jbpm is throwing up exceptions since it cannot deseriliaze object anymore. Prior developer mentioned it and said, I need to delete/clean jbpm tables but I cannot since there are workflow items in there. If I delete them, the users might be a little upset :)
What is the solution ? I am using jbpm 3.2.2 with hibernate 3.3.2 under glassfish 2.1. Thanks.
