Hey Drools Crew,

Business process can be designed to have more the one workitem ( human
task ) with the same name. So two questions here:

1. Confirming: "When registering handlers all of the workitems with
the same name will use the same ( registered to the name ) handler?"

2. What is the way for the client to identify the workitem in this
case? Let's say there is a "truly" parallel definition:

/---> workitem1 ( async send to external
system, waiting for completion )
split ----> workitem2 ( async send to external
system, waiting for completion )
\---> workitem3 ( async send to external
system, waiting for completion )

If workitem1 and workitem3 have the same name, and the response
came back for workitem3, how do the client know to "complete" workitem3 vs.
workitem1?

Workitem IDs are completely workflow / drools-flow related, and
when ( let's say ) approval has returned from an external system, a client
should just tell one of the business workflow services to:

completeApprovalFor( ExternalSystem.SuchAndSuch )

workflow service will have a handler to a workflowInstance
{ businessId, sessionId, processInstanceId, List<Work items in progress>,
etc.. }, so if it is a single workitem the process is waiting for, there is
no problem, but if there are more workitems that make the process to wait +
they may have the same name, it creates a problem.

One solution (for the above specific case) would be to link external
systems with work item ids, so instead of List< Workitems in progress >, it
would be Map< ExternalSystem, Workitem >. But it just looks to complex and
specific...

Anything the framework can help with?

Thank you,
