I have 2 layers (1 polygon / 1 no-geometry (aType)). I have a relation between them.
As we know, we can display 1 value from the related layer via layer property -> Attributes Form.
In the widget type Relation Reference we can select "Display expression" (in my case dispName).
I want to display the dispName as a Simple Label. If I now select the aType as the value for the Label, the display expression is not shown.
How can I have the label of the related field as a simple label?
