Ah, I see that now. The orderBy variable, which is required, is dropped in the map step when docAfter is not null or empty. It’s also dropped when FABefore* or FAAfter* are not null/empty. This definitely explains the symptom you’re seeing as orderBy is expected to be present and when it is not, the NPE is thrown.
Additionally, the call to wm.b2b.editn.FAReport:getFAReportData passes in orderByList, which is never initialized. This service should never work as orderBy will always be null–I can’t figure that part out.
Anyway, this looks to be a bug to me. You could modify generateFAReport to remove the variable dropping to double-check. I think you’ll want to contact tech support in any case.
