The function in the template I suggested is wrong (I think). It doesn't correctly construct the identifier for the list_difference().
Try this:
Code:
return list_difference (ids, strcat(select_identifier, ':', si), ',')
The change is to put a colon between the identifier name and identifier value.
An alternate change that is a bit slower is
Code:
return list_difference (ids, select(ids, select_identifier), ',')
It is slower because it repeats the select().
