I have noticed that when using JBPM with Seam, a DbPersistenceServiceFactory must be configured otherwise a NullPointerException occurs. I know that you can run JBPM by it self without persisence configured and it works just fine. Is there a specific reason why JBPM must be configured with a persistence service in Seam. If not, there is a simple null check that can be done in the org.jboss.seam.bpm.Jbpm.initJbpmConfiguration() method to fix my problems.
