TYPO3 Core

My scenario:

I mapped the "pages" table to an extbase model named "Product", using a custom doktype. So in ext_typoscript_setup.typoscript I have something like this:

config.tx_extbase {
    persistence {
        classes {
            LFM\MyProducts\Domain\Model\Product {
                mapping {
                    tableName = pages
                    recordType = 133
                    columns {
                        doktype.mapOnProperty = doktype
                        l10n_parent.mapOnProperty = parentRecord
                    }
                }
            }
        }
    }
}

This works fine, until I try to read records using a "ProductRepository".

Let's say, we got a "product" page with uid=5, and a translation of that page, with uid=6 and l10n_parent=5.

Using productRepository->findAll() in context of default language, everything works as expected. Product object with uid=5 is returned. In context of the translated language, the findAll method however returns an object that has uid set to 6 instead of 5, and _localizedUid is set to 6 as well.

I tried to test the same with a "normal" Dummy model that is mapped to a regular "tx_myproducts_domain_model_dummy" table. Using that, everything works exactly as expected. (having default language uid=1 and translation uid=2, findAll() returns uid=1 in both default language context as well as translated context, with only _localizedUid having value 2 in translated context).

The primary suspect seems to be the method \TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbBackend::overlayLanguageAndWorkspace.

Some tests have shown that extbase always fetches the translated records in translated context. So the passed $rows array in that overlayLanguageAndWorkspace method contains a list of translated page records. For non-pages records it seems there is a "fix" to pretend to be a default language record, before calling getRecordOverlay, but the same thing is not done for pages record. Instead getPageOverlay is called directly with the (presumably incorrect) translated records.
