[jbpm-dev] Re- IOR gateway

[Anurag Aggarwal]

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

Regards, Anurag
