Empty result with findAll in FlexForm UserFunc in TYPO3 7.6.15 - repository

Question

I get an empty result with findAll in FlexForm UserFunc in TYPO3 7.6.15.
The storagePid is set and in Frontend I get all results with findAll.
Here is my UserFunc-Method:
public function getBuldingOptions(&$config)
{
/** #var ObjectManager $om */
$om = GeneralUtility::makeInstance(ObjectManager::class);
/** #var BuildingRepository $repo */
$repo = $om->get(BuildingRepository::class);
$building = $repo->findAll();
DebuggerUtility::var_dump($building, '$building'); // Output: TYPO3\CMS\Extbase\Persistence\Generic\QueryResultprototypeobject (empty)
// add empty value option
$config['items'][] = [LocalizationUtility::translate('BuildingUserFunc.building.emtpyValue', $this->extName), 0];
/** #var Building $entity */
foreach ($building as $entity) {
$config['items'][] = [$entity->getName(), $entity->getUid()];
}
return $config;
}
What can by still wrong? Anybody an idea?

I've found the problem and a suitable solution.
The problem is, that the configured storagePid does not work in plugin configuration scope. You have to solve the storagePid manually.
I have wrote a service for that and added to EXT:xm_tools:
https://github.com/xima-media/xm_tools/blob/rc-1.0.0/Classes/Extensionmanager/ExtensionUtility.php
And my repository have a initializeObject method:
use TYPO3\CMS\Extbase\Persistence\Generic\Typo3QuerySettings;
use TYPO3\CMS\Extbase\Persistence\Repository;
use Xima\XmTools\Extensionmanager\ExtensionUtility;
class BaseRepository extends Repository
{
private $extName = 'my_extension_key';
public function initializeObject()
{
$pluginSetup = ExtensionUtility::getTypoScriptPluginSetup($this->extName);
/** #var Typo3QuerySettings $querySettings */
$querySettings = $this->objectManager->get(Typo3QuerySettings::class);
$querySettings->setStoragePageIds(array_merge($querySettings->getStoragePageIds(), explode(',', $pluginSetup['persistence']['storagePid'])));
$this->setDefaultQuerySettings($querySettings);
}
}
