[jboss-user] [JBoss jBPM] - Dynamic Process Instances

After evaluating JBPM and walking through a few use cases I have determined that the inability to quickly modify workflow instances is a problem.  In classic workflow there is a workflow definition of which instances are instatiated (sound familiar - like class/object). However, it is often necessary to modify the workflow instances on the fly.  For example if you have 5 chapters in which the "first draft" has to be done by technical writers before you proceed to "full document review", then you have 5 tasks in workflow which converge into a "join" in workflow which then go into a single "review entire document" task.  Unfortunately, if half way through (as happens in writing) you discover you need 8 chapters, it is difficult to modify the workflow instance.  This is because the workflow instance is based on a workflow def which only had 5 tasks.  Basically this is a large problem.  Am I missing something obvious? How could I do this in JBPM.  Seems like we need a sub process that can have an arbitrary number of tasks?
