Looking into the to me known possibilities to hook up against the working memory without really needing to extend core functionality, I reckon my best shot is the org.drools.event.process.ProcessEventListener. Unfortunately I can't seem to find an event that holds information about the new or terminating Sub-Process and the associated parent process. I looked into the beforeNodeTriggered, afterNodeTriggered, BeforeNodeLeft, afterNodeLeft, beforeProcessStarted, afterProcessStarted events but no dice.
events in order of triggering
master process - beforeProcessStarted: no information
subProcessNode - beforeNodeTriggered: subProcessNode has neither sub process name nor subProcessID available
subProcess - beforeProcessStarted: has the sub-Processname/id but no reference to the parent process
subProcess - afterProcessStarted: has the sub-Processname/id but reference in the external event listener?
subProcessNode - afterNodeTriggered: external event listener has the instanceId of the child process but no object reference, so I'd need to query the runtime?
master process - afterProcessStarted: external event listener has the instanceId of the child process but no object reference, so I'd need to query the runtime?
Anyone has an idea how I'd be able no indicate my users whats the current state of his process if its within a sub-process instance?

Hi,
I checked my process instance info table and all states are in 1 - what would be a condition that this changes to 2 (suspended) or 3 (ended) as currently all ended instances get deleted - is there a configuration option to accumulate these in a history table?
Related to this - the only way to drill down from an process instance to the bottom most sub process instances current task is by loading it into the knowledge session and manually check if the node implements a subprocessnode instance and load that sub process instance and so forth until I get the last node which hasn't a node log with type 1? Would there be a way to query from the process/node logs the current sub-process and current node?
To rephrase: I have the requirement to show in which state a current process is - which with the current console tools will only go as far as the parent flows current node - but that are almost always sub-processes, so what I'd need is a way to build a query (or a set of queries) that would reflect the current process instance hierarchy and the current bottom most process/node.
I CAN do this by reading all current instances of a given parent task and afterwards do the individual drill-down until I reach the bottom most sub task - but this is desperately slow for thousands of instances, so I'm looking for a DB select as I reckon all the info is in the audit tables.
