[rules-users] Drools SubFlow (Sub -Process) query API

[Doshi, Bhadresh]

Hi Kris,

I do not see method to access SubProcessNodeInstance from process
instance...

I see only following getters....

ProcessInstance pi = ksession.getProcessInstance(111);
			pi.getClass()
			pi.getEventTypes()
			pi.getId()
			pi.getProcessId()
			pi.getProcessName()
			pi.getState()


Am I missing something... Can you point to sample code?

Thanks,

There is no one method API to do this at this point.  However, if you
have a process instance that is waiting for a sub-process to complete,
there always is a SubProcessNodeInstance as part of the parent process
instance that contains the info you need.

So what you could do is iterate over the node instances of the parent
process instance using WorkflowProcessInstance.getNodeInstances() and
retrieve the information you need using
SubProcessNodeInstance.getProcessInstanceId().

You can probably implement this as a utility method that simply uses the
existing API.
