SilverStripe Fluent - DataObject Live version not created

Question

On SS 4.0.3 only for DataObjects (has-many relation), the DB Localised_Live table version isn't created during save on CMS-side. This result in NULL content on the front-end page.

If I log as admin and inspect one of the pages involved (actually same for 3 distinct DataObjects) in draft mode, I see the contents regularly.

Here's a couple of screenshots:

Here's the code involved (just picking 1 of 3 - are the same):

DataObject

        $uploadFoto->getValidator()->setAllowedExtensions(array('jpg', 'jpeg', 'png', 'gif'));
        $uploadFoto->getValidator()->setAllowedMaxFileSize($dimensioneFoto);

        Folder::find_or_make($cartellaHome);

Answer 1

Issue solved. The missing $owns SiteTree property (see the doc - file ownership), in relation with the DataObjects involved, were the cause that was preventing the contents to be published (files and images especially).
