Null values not displaying in the LOV on the parameter form.

Question

My report works perfect while in Oracle Reports 10g, however when I move it to our menu (Oracle Forms 10g) it does not display the null in the LOV on the parameter form.
This report allows the the user to select by inspector or district or everyone for certain dates.
Ex: I have 4 parameter fields. The user must enter the start & end dates and either the Inspector or the district or leave the inspector or district null to run for everyone.
The district LOV is :
select dnr_section_code, description from dnr_section_code where dnr_section_code in ('29', '38','52')
UNION
select null, 'All' from dual
order by 2 asc ;
The inspector LOV is:
select null , 'All' from dual
UNION
select person_seq, first_name||' '||last_name inspector from vw_eng_inspectors
order by 2 asc
In my Data Model query I use the :
My select
from tables
where clause
+
----by inspector
and (prod_fac_inspections.person_seq_inspector =
nvl(:inspector,prod_fac_inspections.person_seq_inspector))
---by district
and
(d.dnr_section_code = nvl(:district,d.dnr_section_code)
and d.person_seq = prod_fac_inspections.person_seq_inspector)
Again, it works perfect in Reports! It eliminates having 3 reports on the menu. This one report gives the user the option of selecting dynamic parameters.
Also, I got so frustrated, that I went a different route of using a default where.
I am stuck with the error of ORA:00933 SQL command not ended properly
1=1
I set the initial value to 1=1 and it does not like it.
I am stuck!

Hi Krishna,
I'm not sure I understand the probelm.
A progress bar control only displays numeric values. When do you mean by "unassigned values"? What would you expect to be presented?
