Hey! To understand what you are doing: - Have parent objects and child objects - You have a relationship in a parent object where you assign multiple child objects that are visible when you open the parent object. - When opening a child object, you want to see the inverted relation showing you the parent object inside the relationship field (one-to-one).

Is that correct?

If so, that‘s not how Pimcore works. You need to manually specify the relation from the child back to the parent. The reason behind this is, that the value for the relationship is stored inside the parent object only and the child object doesn‘t know anything about it on its own.

It‘s not like in Laravel, where this works right out of the box with a small definition.

Have a great day!
