NPE when using JBPM in Seam without a DbPersistenceServiceFactory confirgured ----------------------------------------------------------------------------- Key: JBSEAM-2312 URL: http://jira.jboss.com/jira/browse/JBSEAM-2312 Project: JBoss Seam Issue Type: Bug Components: BPM Affects Versions: 2.0.0.GA Reporter: David Heggie Priority: Minor I have noticed that when using JBPM with Seam, a DbPersistenceServiceFactory must be configured in the jbpm.cfg.xml, 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. Also the Jbpm class has a few dependancies on Hibernate that would be nice to remove as it is annoying to include the whole jar just for 2-3 classes.
