    protected function fetchRelatedEager(Tx_Extbase_DomainObject_DomainObjectInterface $parentObject, $propertyName, $fieldValue = '') {
-               if ($fieldValue === '') return array();
+//             if ($fieldValue === '') return array();
        $query = $this->getPreparedQuery($parentObject, $propertyName, $fieldValue);
        return $query->execute();
    }

Tested, works. :)

I cannot confirm the patch works problem seems to be in the thawProperties-method wich checks the column value against null before doing anything. That might be usefull for anything else except many to many relations, but if you keep the null value vor a collection field / Tx_Extbase_Persistence_ObjectStorage and you're trying to access it later on it's messy. Furthermore one cannot trust the relation field to contain the correct relation count as it's very likely to be wrong see http://forge.typo3.org/issues/23980 for more information.

poke Any updates on this? Thanks! :)

Probably already fixed? See #23980 for more information.

Finding the objects seems to work with the
new property manager, but if you remove the
object via $repository->remove($object); the
record in the MM table gets deleted but the
"counters" of both tables will stay the same.

So after the removing of the objects, the
counter is not decreased in the "origin" objects.

Not sure if this is intended.
