When inventing terms (strings) during desugaring, they do not have a NaBL2 attachment.

Before desugaring:

module debug

  model
    entity Student {
    }
    entity Course { }
    relation Enrollment {
      Student *
      Course *
      
      course.students <-> student.courses
    }

After desugaring:

module debug

model

  entity Student {
  }

  entity Course {
  }

  relation Enrollment {
    Student.enrollment *(unordered) -> student
    Course.enrollment *(unordered) -> course
    course.students <-> student.courses
  }

Error if processing non-desugared example:

19:19 | INFO  | stderr                         - The following terms do not have an nabl2 attachment ["enrollment","student","enrollment","course"]

Suggested fix: add attachments to AST nodes after desugaring, rather than before.

Attaching indices are already being attached after desugaring. I think the problem is that custom analysis was passed the original AST instead of the desugared one. I’ve pushed a small fix that passes the desugared to custom analysis, so I expect that should fix this.

I’m closing this for now, but please reopen if the issue is not solved by the next build.
