Batch moving category for sermon causes Undefined property

Dear Thomas,

My freshly installed:
Joomla 3.8.5; SermonSpeaker 5.7.1; PHP 7.1.12
At Sermon Manager, I check some sermons, batch Operation, Move Category.
For each sermon operated, an entry is added at the Apache error log:
PHP Notice: Undefined property: SermonspeakerModelSermon::$typeAlias in /var/www/DocRoot/libraries/src/MVC/Model/AdminModel.php on line 605, referer: mysite.com/administrator/index.php?optio...speaker&view=sermons
Moving categories is done but the error logs are nuisance. Would you kindly look at that?

Thank you.

Ken

Thanks for the notice. I'll have a look where this comes from.
To avoid to see those notices, you can disable the errror logging in your Joomla configuration. That should be done anyway on a productive site.

It's actually two bugs.
One in Joomla itself: github.com/joomla/joomla-cms/pull/19647
And another one in SermonSpeaker: github.com/Bakual/SermonSpeaker/commit/f...9fc89f963b086c954124

The fix will be in SermonSpeaker 5.8.0.
