Body
I was using Custom Form elements in my application so I started to work through all the tips in the Advanced Form guide. Despite implementing all of these points, I was still getting an error. Thanks to a reference example, I found that I could resolve my errors with one additional change not documented in the guide:

You must also define the form (not just the custom elements) inside form_elements rather than service_manager otherwise init() is not run

If this is a requirement, it would be helpful to add it to the guide. If this should not be a requirement, I may need to submit a bug report.
