TYPO3 Core

I used the TYPO3 8.6.1 - build via composer 6.3.2017
XAMPP PHP 7.0.5

Scenario:
- My Extension define some content-elements
- I have a content-element with an own model
- The CE has an 1:1 IRRE relation to an other model.
- If I try to create the IRRE-Relation in the backend in the default language, i se the estimated form
- If I try to save the created IRRE-Element, I got the exception below
- If I try to create the Element with my own frontend-editing (extbase; create Action with dummy-element-generation), the IRRE will be shown after that in the backend
- After I created the IRRE for the default language with my frontend-mechanism, I can use the feature of synchronisation of records for the other languages and it seems to work fine

Exception:
