Dear Community,
With the support I've been receiving from the community members & developers, I
have involved myself into this wonderful phenomenon of exploring and making the best use
of jBPM5 & BPMN2.0
My current experiment is to combine User Task with Multiple Instances construct involving
looping mechanism for an iterative execution. I'm good with generation of multiple
task items (User task in my case) sequentially and its completion synchrounously and
execution out of Multiple Instances construct is also fine.

*Objective* of my above depicted design is to reduce a lot of manual effort in placing
multiple user tasks to achieve a approval workflow of multi levels with more than an user
task at every level.
1) To serve the horizontal purpose I'm simply using Multiple Instances node to create
concurrent user task assignments.
2) To carry out the vertical level I have manually introduced the looping mechanism.
*Concerns & Queries* about what I'm trying to achieve is
1) If at all I have placed separate User Tasks across the BPMN, associating the name of
the tasks with User Task node would have become simple since I would have given the names
separately. But in case of my design the User Task which takes the input with the help of
Multiple Instances node's collection expression(list) it gets the User (Approver) name
alone. I'm wondering how can I associate the name of the task with the User Task node.
For Eg:- HR Approval, Admin Approval etc., If the multiple instances node is capable of
taking Map object we could have set the Task Name as key and the User name as value.
2) Is there any tweak available for Multiple Instances node with which we can set its
property to "Async" because the construct behaves in a synchronized manner
meaning only after all the Task assignments(User task in my case) are completed the
construct moves forward its control. But there are situations in which I really need to
keep the User Tasks triggered out of Multiple Instances be independent of each other.
3) Is it possible to customize the User Task to associate it with an WorkItemHandler.
This question should make sense if my understanding about the Domain specific
WorkItemHandlers are not wrong.
Guys, please throw me some light on these things as I'm struct and not able to move
forward with the other things..
Thanks in Advance,
Aadav
