[rules-users] Resuming the Flow: SESSION_ID, PROCESS_INSTANCE_ID, WORKITEM_ID

[Mauricio Salatino]

1) calling ((WorkItemNode)
processInstance.getNodeInstances() will return the list of current Node
Instances inside the process.
This means that you can retrieve for each of them the name and compare to
know which one do you want to complete.

2) A session can contain multiple process instances inside it. it depends on
the information that you want to store inside each session. Depending on
your use case is how you will divide: one process Instance per session,
multiple process instances per session, etc.
