Dependant LOVs on Customization form of a report

Question

Portal Version: 3.0.9.8.0
Database Version: 8.1.7.3
Hi
Our problem is that we've created a report component which includes two bind variables. These bind variables are chosen on the customization form through LOVs. The second LOV needs to be dependant on the first. Here's the code of the report and LOVs:
REPORT
select * from SHARE_DATA A, SHARE_INSTRUMENTS B, COMPANIES C, INDUSTRIES D
where D.SYSTEM_ID = :Industry
and C.SYSTEM_ID = :Company
and C.SYSTEM_ID = A.CPY_SYSTEM_ID
and A.SIN_SYSTEM_ID = B.SYSTEM_ID
and C.IND_SYSTEM_ID = D.SYSTEM_ID
where bind variables :Industry and :Company are linked to the following LOVs
LOV_INDUSTRIES
select (INDUSTRY_NAME||' '||SECTOR_NAME) industry_sector, (SYSTEM_ID)
from INDUSTRIES
order by industry_sector
LOV_COMPANIES
select A.NAME name, A.SYSTEM_ID
from COMPANIES A
where IND_SYSTEM_ID = :Industry
order by name
LOV_COMPANIES is dependant on LOV_INDUSTRIES.
We receive the following error message when opening up the customization form:
COMBOBOX LOV ERROR:
LOV: "APP_ACIA.LOV_COMPANIES"
Parse Message: Parse as pre-set global: "ACIA".
Find Message: LOV is of type DYNAMIC (LOV based on SQL query).
Query: "select A.NAME name, A.SYSTEM_ID from COMPANIES A where IND_SYSTEM_ID = :Industry order by name "

Hi,
The error is thrown because the lov is not able to substitute the value for the bind variable. The substitution is not happening
because depandant lovs are not supported in Portal Reports.
Thanks,
