I'll be the first to admit, I've had more than a tiny bit of difficulty using jBPM as our workflow solution. I had several issues with timer and subProcessInstance persistence with 3.0.2, so I switched today to 3.1. However, now I'm having some problems I didn't have before, even before I've worked out the ones I did have. :)
I listed one problem with process definition deployment here: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77406 I'm still having problems with persistence: it appears that in the database my tokens have null processInstance_, parent_, and subProcessInstance_ fields, and the ProcessInstance rows have null superProcessToken_ fields. What confuses me is that in my current persistence problems the rows are being saved in the database, but those key parts are missing. I'm trying to use jBPM in a clustered JBoss 4.0.3 environment, and the processes I've designed so far use timers and subprocesses significantly. (Here's a previous post describing some of my timer trouble: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77192). I've tried to tell jBPM about my transactions with this in hibernate.cfg.xml: <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> | <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property> | My workflows are all fairly complex (and long), but I've tested them using a web application and they all seem to work. However, going to JBoss seems to introduce a fair amount of trouble. Are there restrictions on what can go on within one transaction? For instance, my application creates a process instance, starts it with a signal(), and according to workflow rules it advances into a subprocess which creates a timer for later automatic advancement, *all* before the session bean returns and the transaction ends. Does that have any effect on persistence? If anyone has any ideas on this, or any information about exactly how and where I should be saving (now via jbpmContext.save()) things, please let me know.
