Gateway in the branch of another gateway

Question

In the setup of an e-form. We require a gateway in the branch of another gateway. However i'm not getting this to work properly. Is this possible? How do I achieve this?

What i have is the following:

My first gateway has 2 branches. Of which the first branch is an approval task. After this approval task, the form needs to be sent to a certain emailaddress without waiting on the other branch.

In the second branch. I have another gateway with 8 branches which each contain an approval task. These tasks DO have to wait for each other to be completed before sending the email.

So this is why I would need these 2 gateways.

However when i implement this and test it the recording stops just in front of the second gateway without any error message.

Any ideas how to fix/implement this?

Gateway 1

Gateway 2 (in Other Approvals Process):

Both have all branches setup synchronous:

When I Playback the recording for "Other Approvals", the process seems to stop before entering the second gateway:

Apparently i seem to get following error now:

    Cannot execute a split on transactional branch.

Answer 1

I've found the issue!

Apparently my subprocess "Other Approvals" was still configured as a short-lived process. This caused the flow to generate a Fatal error.

By adding an approval task to the process, the process was automatically converted to a long-lived process. Afterwards I removed the approval task. And redeployed the application. This solved the issue and made the flow work.
