That's what I mention. it can be easy to implement most of the times but there are also some complex business use case that can complicate the generic approaches.Looking at a concrete use case will help a lot to understand what do you want to achieve.

just some general remarks from my side:
the semantics and implementation of the inclusive OR-join are far from trivial. See e.g. references below.

However, I’d be interested in the concrete business requirement you have for modeling, since from my experience you can cover a very large part of regular requirements just using the “simple” gateways.

Hi Anurag,
Based on your description I think that I'm understanding what do you want to do now.
Right now the behaviors implemented in jBPM5 are XOR and AND.
I think what you want to implement is N of M converging gateway, as it was in Drools Flow? Am I right?
You want to wait 2 of the 3 branches that you have to propagate the execution?
Cheers

Hi Mauricio,
If an an AND converging gateway has n incoming branches, it expects that all incoming have been triggered and when it is so - it calls triggerCompleted (so that the rest of the process can continue)
In case of OR converging, lets assume a process
branch1
/ \
OR (diverging) - branch 2 - OR (converging)
\ /
branch 3
now any of branches may be triggered, OR converging has to wait for all branches that were actually triggered (say branch1 and branch 3). But the problem is it does not know which branches were triggered (for AND it was easier - just wait for all branches to be triggered). here in case of OR - we don't know to continue to wait for branch 2 or not

Hi Antoine,
So do you want to implement and OR or and AND converging gateway, by the description it looks like and AND converging gateway. Is there any differences with the AND converging gateway that is currently implemented in jBPM5?
Cheers

Hi Mauricio, that's an OR converging gateway.

Hi guys.. that's the AND Converging gateway right?
The AND waits for all the branches that are converging before propagate.
If that's not what you are looking for it should be very easy to implement.. and probably you can model that with the complex converge gateway.
Cheers.

Hi Kris,
How are you
Recently one of our requirements came up for converging IOR gateway, this is the gateway which according to bpmn specification syncs up on all upstream tokens and propagates token when no upstream token is left
Currently jbpm does not support this construct, I was wondering if jbom has this in roadmap and if you can give some advice on difficulty and state of implementation
Regards,
Anurag
