JBPM Multi-Instance loop Characteristics with “Sequential instead of Parallel Execution” not working

nishantkparmar Nov 6, 2017 4:15 PM

We have requirement to use generate tasks depends on input variables but Task should be executed in Sequence instead of parallel.

For above requirement

I am using Multi-Instance Sub-process to generate the tasks based on input parameter.
To execute in sequence In process definition I can see there is option in multi-instance sub-process loop characteristics "Sequential instead of Parallel Execution".

I turned it on so that it executes in sequence but on start of sub process it still executing in parallel (default behavior)

PLEASE HELP

Hello!

I have the same problem. Everything worked before I started using more than just 1 thread. Now I use 4, and many instances of the multi-instance process start at the same time. Not sequential at all.
Weird solution: use gateways to create the loop

I was wrong! This happens since I have started using Executor

So, how to solve this problem? Or don't use jbpm-executor is only solution?
