[rules-users] Determining the active nodeinstance for a process

I'm trying to determine 'where' a process is (not the active/completed/ etc. state), but the wait state. One way of doing this (and tracing the process execution) would be via a RuleFlowEventListener; however is there a way to query a ProcessInstance (or something?) for this information? Effectively I want to know which EventBasedNodeInstances are triggered for a process and waiting for a response. Use case is to show in a user interface what the process is waiting for (i.e. loan approval, timeout, some confirmation). Furthermore, I am confused as to where a process resumes after being marshalled from db back into memory. I can see that there is a 'reconnect' method which gets called, but it looks like the implementation of this calls the start Node again!?! Thanks, Garrett
