> When deleting an ObjEntity with flattened attributes Cayenne deletes the related DB attribute's row as well.
>  
> So if we have for example an ObjEntity "FlatPainting" with flattened attribute "galleryName". If we then delete a "FlatPainting" then the associated gallery will also be deleted, leaving all other paintings at that gallery without a valid Gallery link.
>  
> Furthermore if we add to our "FlatPainting" a "gallery" relationship attribute with delete rule Deny, the gallery is still deleted.
