Tested on https://demo.dmx.systems. I created a new Composite "Motor" and added some child attributes. When I now create Motor Topics and save them, the value of "Ventilbezeichnung" is not being displayed. Only when I click anywhere in the white space map or reload the page an then view the details again, the value of "Ventilbezeichnung" is displayed.

Note: Effect is true for in map details as well as the details panel. Effect is repeatable when either creating new motor topics or when adding new "Zylinder" to existing ones.

Situation immediately after saving the information

Situation after click in white space and re-selecting the topic
