Problems with 4.1.1.00.23 Cascading LOVs

Question

I have a pages with 4 levels of cascading LOVs. These are:
MEMBER_ID => ACCOUNT => COMMODITY => EXPIRY
The issue I am running into is that these work fine up through the first three and then fails (or rather simply doesn't do anything) on EXPIRY. I have no idea what or what to do to get this last level to populate. I have confirmed, using the values present in the session that the query for EXPIRY should return data.
The top level is a simply Select List Control using a Named LOV with this query:
select
case organization_type
  when 'Member' then NAME || Chr(32) || LEGAL_NAME
  when 'Bank' then LEGAL_NAME
end d,
ID r
from mbrdata.ORGANIZATION
order by name, legal_nameThe next level, ACCOUNT, is set up as a cascading LOV. The parent is the MEMBER_ID.

Hi Joe,
looks like you don't reference the parent lov's items in the sql queries for ACCOUNT, COMMODITY and EXPIRY.
Are there any processes (DA, Ajax etc.) that you use to populate the items :P15_MEMBER_OR_TRADER, :P15_MARGINING_ACCOUNT and :P15_PHYSICAL_COMMODITY in those queries?
