Hi Stefan Helzle
Thank You. This is exactly what we observed however we did not find any documentation to back that up.
Do you know of any other nodes / smart services that can do the same?

Thanks

I was afraid thats gonna be the case. Thanks!

A rule event is made for a different purpose and will break chaining.

In scenarios in which I need to wait for 1-n parallel flows, I start all of them, but include the skipping and merging logic in each parallel flow. This way I can just wait for all of them in a simple AND.

Hi Łukasz Kolmer ,

Activity Chaining is considered to make process complete faster when there are no breaks needed, you had activity chaining all throughtout the process model.

Activity chain breaks when the node waits for 5 or more seconds and the process will be on hold, never goes forward.

your rule event may be taking some time to process, but the only solution is to take off chaining where the node continues to take some time to evaluate.

try to optimize the nodes, and put proper chaining where the node doesn't take much time to proceed further.

Activity chaining used when there is a requirement of successive form-completion by the same user. I don't see any Screens (User input tasks) in your Flow, Do you have any UIT's in Subprocess??. I don't recommend activity chaining if you don't have user screens (It leads to Performance issues).

[quote userid="199816" url="~/discussions/f/process/35543/rule-event-and-activity-chaining"] I've got to wait for all incoming 0 to 4 flows to finish and then start the Statuses PM, [/quote]

Activity chaining's gonna break when there is wait time of more than 5 seconds. You need to make sure that all paths are completing before 5 secs. I don't know exactly but try using Complex gateway (Select wait for n of n Paths to arrive before processing).
