It would be nice if the ListExploder could work with irregular lists instead of rejecting them with fme_rejection_code' has value `MISSING_PARAMETER_LIST'.
An irregular list is a list that either does not start at 0 or does not have continuous indexes.
ex.
_list{1}
_list{2}
_list{3}
or
_list{0}
_list{2}
_list{3}
_list{5}

ListExploder to work with irregular lists

+1 for this suggestion
As a workaround I tried listCopier but the irregular indexes were copied along. However applying a ListSorter using an arbitrary list attribute and than applying the list exploder actually didn't result in the MISSING_PARAMETER_LIST error any longer.
Sorting of course has its performance cost, so it would be good to foresee a solution within the listExploder transformer.
+1I had the same problem, I was reading from a CSV, and building lists from it, I realised that by importing the CSV and reading blank cells as NULL rather than missing I was not getting any `MISSING_PARAMETER_LIST'. on my ListExploder.
Once I exploded the list I filtered out the NULL records.
