We had this once (i think it was called a milestone in jbpm 2).  But probably it didn't make it to jbpm 3.  I'll make sure this will re-enter in jbpm 4.

This is the same as the links in BPEL, right ?

Actually, what you need for this is variable colletion support :-)  This requirement can be handled with 1 process variables e.g. called 'purposes' which is a collection of ProcessInstance's.  jBPM is able to persist references to 'hibernatable' objects in the process variables.  But jBPM doesn't yet handle collections.  Meaning that if you put a collection of hibernatable objects as a process variable, this will be recognized as a serializable and the serialized value (a large one in case of a collection of process instances), will be stored in binary format in the db.

I'll try to add collection support in jbpm 4.  Or do you think there is another (better) way of handling this requirement.?
