External LOV Problem

Question

Dear Users,
I have defined an external lov and attached this lov to a field on the page.
While creating the external lov I 've tested the query on the database and it was returning rows. I tested the query in JDev as well while creating the external lov and it passed the test.
When I have run the page and when I am trying to select the value from the LOV it is returning zero rows. Message is no rows to display.
But when I am executing the query in back end is returning rows.
How to debug this problem.
Kindly please help me to resolve the above issue.
Many thanks in advance.
Best Regards,
Arun Reddy D.

Hello Anand,
Thanks again for your reply.
What is the change you have done ?
Previously my query was extracting assets from Book A1. I just changed the value to Book B1.
Make sure attribute mappings are correct of the LOV VO.
I cross checked the attribute mappings again and all are correct.
Make sure that there are no bind variables in the LOV VO. Otherwise you need to execute the VO programatically.
There are no bind variables in the query. It is a simple SQL Query
Query is as follows:
select a.ASSET_ID,
a.ASSET_NUMBER,
a.DESCRIPTION,
b.cost,
l.location_id,
l.segment1,
l.segment2,
l.segment3,
l.segment4
from fa_additions_v          a,
fa_books                b,
fa_asset_keywords       k,
fa_distribution_history d,
fa_locations            l
where b.asset_id = a.ASSET_ID
and b.date_ineffective is null
and b.book_type_code = 'B1'
and k.code_combination_id = a.ASSET_KEY_CCID
and d.asset_id = a.ASSET_ID
and d.date_ineffective is null
and l.location_id = d.location_id
When you open the LOV window and search for some data, are you not getting any data ?
Yes you are right. When I am searching the LOV there is no data.
Create a LOV CO and in the processFormRequest of this CO, get the query using vo.getQuery() and check.
I did this and it returned the same query which I have given above. when I am executing this query in back end it is giving data.
Kindly please help me in resolving this issue.
Many thanks in advance.
