Gavin King commented on JBSEAM-256:
-----------------------------------

What I'm talking about is the ability for a process instance to have a special "business key", ie a natural unique key in the database.

So you would have:

   String key = currentOrder.getId().toString();
   processDefinition.createProcessInstance(key);

Or perhaps simply:

   String key = currentOrder.getId().toString();
   processInstance.setKey(key);

And then, in another part of the code, you can do:

   String key = currentOrder.getId().toString();
   context.findProcessDefinitionByKey(key);

And the database table has a unique constraint on (processDefnName, key).

Obviously the slightly sucky part about this is that the user needs to be able to stringify the PK of their business objects, but in practice that is very easy to do.
