I really like the idea of having the ability to retrieve the actual business object from a ProcessInstance. That is a nice touch. anonymous wrote : ...the combination (processDefinition, businessKey) must be unique ... Actually, while this doesn't address part of the scenario I constructed (one business object being represented by multiple processes), it is workable as long as the various processes can be 'wrapped' in a single parent process that represents the business object one-to-one. However, in that scenario, it would be much easier if the developer could simply declare in each process definition exaclty which business concept is being represented rather than go through the excercise of creating a single parent process and the logic to select one of several sub-process. Of course, in my solution, a single process doesn't readily serve multiple business objects, but I'm having a hard time thinking of a case in which one would.
