User development, A new message was posted in the thread "Upgrade from JBPM3 to JBPM4 woes": http://community.jboss.org/message/523946#523946 Author : nick bauman Profile : http://community.jboss.org/people/nick.bauman Message: -------------------------------------------------------------- Anand, Thanks I saw that. I'll probabaly use that at some point. I'm more interested in the integration code I have that interacts with the internals of the workflow engine: where GraphElement, Node, State, Transition, ExecutionContext may have gone or how they've changed? I've since figured out what happened with ActionHandler: It became ActivityBehavior. Another one: ContextInstance became ActivityExecution. These two changes weren't too hard to sort out. The hard questions begin to arise where our use of JbpmTemplate to integrate with Spring is utterly broken because of how JBPM4 integrates with Spring. Any tips on migration here would be helpful, too. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523946#523946
