Mauricio Salatino [http://community.jboss.org/people/salaboy21] created the discussion "Re: Difference between org.drools.runtime.process.ProcessInstance and org.drools.runtime.process.WorkflowProcessInstance" To view the discussion, visit: http://community.jboss.org/message/631356#631356 -------------------------------------------------------------- Process instance is a more abstract concept about process only, not rules or decision tables. Imagine that you want to run another type of process with the engine you just need to plug that there as an implementation of ProcessInstance. For example if you want to run an instance of a process with a different set of nodes (different execution semantic) you can add your own implementation there.
