[Question]: Relations with two referenced and referencing Fields

[d0rbay]

What is the question?

In my QGIS Project i have configured a 1:N relation between two layers using two referenced and referencing Fields. Opening up the Parent Feature Attributes in QGIS only child features where both referencing Fields match will show up as expected.

I also configured the relation in Lizmap. When opening up the parent pop up in Lizmap web client only the first of the two referenced and referencing Fields will be used to establish the 1:N relation between the two layers.

Is it possible to use two referenced and referencing Fields for a relation in Lizmap web client?

Did I formulate my Question clearly enough? Is this an behavior that should work in Lizmap or a feature that has not been added yet?
