The relationship calculation as a secondary control (column) is not the most important data on the user side for this addon tool. The primary goal was to retrieve pure associations records from user data, as displayed on editors. The feeling of a layout bug might be this secondary test control (column) via the built-in localized relationships handler?
Sure, could be confusing as mixing two different data set or methods. One has been filled by the user and the second one is a simple calculation (or the machine one).
Maybe I also did a mistake on the primary or starting person for the relation. So, there is maybe at least two issues!
Note, there is now a quicker way to check these associations…
for person in people():
for ref in person.references:
row(person, ref.rel, ref.reference)
