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

[Mauricio Salatino]

Hi,
1) if you have subprocesses and you ask for your node instances in the
Parent Process you will get a Node of type SubProcessNode, you will not get
all the work items related inside it. You need to use the sub process id and
then get all the node instances inside it to see which work items needs to
be completed

2) yes it is accuarate. You always need a session, because the
ProcessInstances lives inside a session.
