Project forms_one-to-many-relations seems malformed

[tomasMizera]

When I open the documentation/forms_one-to-many-relations project, I do not see any value in the relation reference field (child feature's link to parent).

See Manhole ID on the image below.

Closer look revealed that the field config does not contain some of the important information:

• config from a working project

QMap(("AllowAddFeatures", QVariant(bool, false))("AllowNULL", QVariant(bool, true))("MapIdentification", QVariant(bool, false))("OrderByValue", QVariant(bool, false))("ReadOnly", QVariant(bool, false))("ReferencedLayerDataSource", QVariant(QString, "/home/shockwave/Lutra/projects/test_input/23.8./tc05_relations/db.gpkg|layername=district"))("ReferencedLayerId", QVariant(QString, "db_district_03d52629_f825_45d6_9ee5_8da8552b9987"))("ReferencedLayerName", QVariant(QString, "districts"))("ReferencedLayerProviderKey", QVariant(QString, "ogr"))("Relation", QVariant(QString, "district_n_district_fk_db_distric_fid"))("ShowForm", QVariant(bool, false))("ShowOpenFormButton", QVariant(bool, true)))

• config from this project:

QMap(("IsMultiline", QVariant(bool, false))("Relation", QVariant(QString, "inspection_manhole-id_manhole_lo_unique-id"))("UseHtml", QVariant(bool, false)))

Let's see what is going on here.
