Hi,I have a workflow that has a user task followed by a java service task. I ran a test where the task was completed, after which the java service task ran, which threw an exception (due to a data error on my part). My expectation was that the task itself would be complete (because it had to be co

Does this mean that we can rely on having a single transaction for a sequence of constructs that don't contain a wait construct? If so, is this the long-term behavior, or is it subject to change as the engine evolves?

Thanks,

Yes

Both, since it is a non-bpmn construct, it might be subject to (small) changes/improvements I think, but stable enough to rely on it for llong term
