[TYPO3-mvc] 6.2: How to debug recursive validation

[g4-lisz at tonarchiv.ch]

Hi Matthew,

that's where I started trying to find the issue...

I wonder why the error message doesn't tell where the validation fails.

The parameter/object handed to the action is correct, so it must be a
validation issue...

But why does it work when beeing called from a plugin COA. But from
typoscript userfunc it doesn't?

Why did it work in T3 4.6?

The domain object in question has so many depencies... I don't know
where to start. Hence my question still remains: How can I debug the
validation? Is there a way to make the errors a little bit more
communicative?

Cheers,
Till
