Htmldb_item(s) are null but return query values

Question

Hi,
I have used the following query to create a region (I've done many like this).
When I access the htmldb_application items in insert statements it works fine.
But, when I try to do an update statement the htmldb_application items are null;
even after returning & displaying the values on screen. Hope this makes sense.
Region:
Select x.establishment_name,
x.hsd_insurance_policy_number,
x.hsd_insurance_group,
x.del
from
(Select
htmldb_item.text(11,establishment_name,20) establishment_name,
htmldb_item.text(12,hsd_insurance_policy_number) hsd_insurance_policy_number,
htmldb_item.text(13,hsd_insurance_group) hsd_insurance_group,
htmldb_item.hidden(14,hsd_person_insurance_id) hsd_person_insurance_id,
htmldb_item.hidden(15,gen_establishment_id) gen_establishment_id,
htmldb_item.hidden(16,gen_adr_id) gen_adr_id,
htmldb_item.checkbox(20,gen_person_id) del
from hsd_insurance_v
where gen_person_id = :HSD_Per_Identifier
union all
Select
htmldb_item.text(11,null),
htmldb_item.text(12,null),
htmldb_item.text(13,null),
htmldb_item.hidden(14,null),
htmldb_item.hidden(15,null),
htmldb_item.hidden(16,null),
htmldb_item.checkbox(20,null) del
from all_objects where rownum < nvl(:P4300_ROWS3,2)) x
Update Statement:
Begin
for i in 1..htmldb_application.g_f11.count
loop
If htmldb_application.g_f11(i) is not null Then
Update HSD_PERSON_INSURANCE
Set
HSD_INSURANCE_POLICY_NUMBER = htmldb_application.g_f12(i),
HSD_INSURANCE_GROUP = htmldb_application.g_f13(i),
LAST_UPDATE_BY = :P4300_Updated_By,
LAST_UPDATE_DATE = to_date(:P4300_Updated_Date,'DD/MM/YYYY')
where
hsd_person_insurance_id = htmldb_application.g_f14(i);
Update Gen_Establishment_Entity
Set
ESTABLISHMENT_NAME = htmldb_application.g_f11(i),
LAST_UPDATE_BY = :P4300_Updated_By,
LAST_UPDATE_DATE = to_date(:P4300_Updated_Date,'DD/MM/YYYY')
where gen_establishment_id = htmldb_application.g_f15(i);
end if;
end loop;
end;

Susan,
In 1.5, htmldb_item.select_list_from_query didn't support "display extra values" behavior. Now it does and a tenth parameter (p_show_extra in varchar2 default 'YES') allows you to disable it with 'NO'.
In your example, the query selects only non-null commisions, but setting p_show_null=>'YES' gives you the first null row and the default setting p_show_extra=>'YES' gives you the last null row, which is the "selected" option for rows where the comm column is null.
Add ,NULL,NULL,'NO' to the function call to eliminate the unwanted row.
