Hi Isomorphic,
Can you please help me shed some light on what might be causing this warning?
Thanks

Generally this would mean that null was passed where a Record or widget was expected. In this case we would guess that you called editRecord(null).

[stonebranch2]

I put a breakpoint directly before the call to ValuesManager.editRecord(Record) that produces the warning, and the Record is definitely not null there.

Provided that information, any hunch as to where I could look further? One interesting fact is that it only produces that warning the very first time editRecord is called. The next time it is called, no warning.

[Isomorphic]

Then it could be a place where you've called an AutoChild configuration API with null.

It's a harmless warning, but if you can provide a way to reproduce it when it shouldn't be happening, we'll take a look.

If it is a "harmless" warning, I will let it be for now.
Thank you
