3.1 Page 0 LOV APP_ITEM issues

Question

Hello,
I recently upgraded from 3.0.1 to 3.1 and my application appears to have broken.
I have a select list on page 0. The LOV query references an application item using the bind syntax. similar to
select col1 d, col2 r
from my_table
where col3 = :MY_APP_ITEM
order by 1
Since upgrading to 3.1, the select lists are empty after submitting the page, even when the session shows a value in my application item.
This problem only manifests in the select list LOV. If i create a display only item with MY_APP_ITEM as the source, it displays fine.
It almost seems like the page 0 LOV queries are parsed before the session is populated on page load.
Has anybody seen this? Any advice?
Thanks in advance

Hi Guys,
I am encountering a similar problem to the one mentioned here. I've tried to create a dynamic LOV as below:-
select state_name AS Display_val, state_abbrev as Return_Val
from Pay_US_States@&DB_LINK_APP_ITEM.
order by 1
but I get the following error message...
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When I change the query to reference the db link directly, it works fine.
select state_name AS Display_val, state_abbrev as Return_Val
from Pay_US_States@dbname_link
order by 1
I am using version 3.1.0.00.32 of APEX and the db link refers to a remote database. APEX itself is installed on a local XE database.
I have other page references to the application item which work fine but using it in LOVs does not seem possible.
The application item is set on my login page (page 211) in the login process as follows...
:DB_LINK_APP_ITEM := :P211_DB_NAME||'_LINK';
wwv_flow_custom_auth_std.login(
P_UNAME => :P211_USERNAME,
P_PASSWORD => :P211_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':2'
Any help would be great!
Thanks,
