Are you sure the usage of parent::canEdit($member) targeting SilverStripe\ORM\DataExtension::canEdit() seems to always return null.

The property ID does not exist on LeKoala\CommonExtensions\LockableExtension. Did you maybe forget to declare it?

The method write() does not exist on LeKoala\CommonExtensions\LockableExtension.
