[TYPO3-mvc] Get orphaned children

["Søren Andersen"]

Hi Phillip,

You say that I should use the right repository, and you suggest the
registration repository. But as I said, I'm already using that repository.

My problem is that a registration can belong to several exports, so
there's not just one parent.

So my question is, in the registration repository, how do I structure a
query to get all registrations with an empty object storage concerning
exports?

I thought that I could check if the field "exports" in the registrations
table was 0. But it seems that Extbase doesn't really update that field
with the number of relations, as the backend does.

Sincerely,
Søren Andersen
