Return value of `SingleEvent::getVenues()` is null

[wegewerk-mdt]

when sending emails after successful registration in RegistrationManager::notifyAttendee an Exception is thrown

Return value of OliverKlee\Seminars\Domain\Model\Event\SingleEvent::getVenues() must be an instance of TYPO3\CMS\Extbase\Persistence\ObjectStorage, null returned

And the function SingleEvent::setVenues() is never called?

Hi @wegewerk-mdt, which versions of TYPO3, seminars and oelib are you using?

[oliverklee]

And is this with or without any XCLASSes?

[wegewerk-mdt]

oliverklee/seminars v5.7.0 oliverklee/oelib 6.0.0 TYPO3 11.5.39

we XCLASSed \OliverKlee\Seminars\OldModel\LegacyEvent and \OliverKlee\Seminars\OldModel\LegacyRegistration

[oliverklee]

@wegewerk-mdt Does the event with which this occur have any related venues?

And if not, does the same problem also occur for you if the event has any venues?

[oliverklee]

I cannot reproduce this with the latest seminars 5.x branch (basically a 5.7.0) on the latest TYPO3 10LTS, and also not with the latest main on the latest TYPO3 11LTS, neither with an event withing venues nor with an event with 1 venue.

@wegewerk-mdt And could you please try these things and check whether they make any difference?

1. clear all TYPO3 caches (either using typo3(cms) cache:flush or the BE)
2. temporarily disable all XCLASSes for seminars
3. temporarily disable all Composer patches for seminars

[wegewerk-mdt]

I tested in a fresh TYPO3 v11 installation and cannot reproduce the error there. Will test in my modified instance (DGE)

Thank you for the quick feedback! :pray:
