Thanks Kris, That seems like the solution I was looking for... I'll try persisting my session ID in my Claims domain object, and walking the node instances first. If that doesn't work, I'll try create a custom log object to track processes. Either way, this thread has been a huge help.

Quoting Bill Tarr <javatestcase(a)yahoo.com&gt;: Yes, cast the process instance to a WorkflowProcessInstance, that way you can use getNodeInstances() to get all active nodes.  You'll then probably have to use instanceof SubProcessNodeInstance to only filter out sub-process nodes, and then use getProcessInstanceId() to retrieve the id of the sub process instance.
