Unexpected problem with authorization scheme of type plsql function

Question

Hi,
I have created one authorization scheme of type plsql function returning boolean. Authorization scheme is for pages only. p2_user_priviledge is a textbox on home page which extract privilege (list of pagenos) for login user from database. Home page has no authorization required. AUTHORIZATION SCHEME always returns false. I am not able to trace problem in my code. same code works fine for a textbox's default returning 'c'.
----- CODE FOR AUTHORIZATION SCHEME------------------------------------------------------------
declare
pageid varchar2(10);
privilege varchar2(300);
c number(3);
begin
pageid := ':P'||to_char(:app_page_id)||':' ; ---Pageno get stored in format  *:P2:*
privilege := trim(:p2_user_priviledge); ++------Contain list of privilege like    :P2:P13:P67:P23:  etc+++ select instr(privilege,pageid) into c from dual;
if c>0 then
return true;
else
return false;
end if;
end;
One more problem is again related to authorization scheme.
I created one application and one authorization scheme (auth_aug) which worked finely. Then after some days i added 10 more pages to same application, But now autho_aug was always returning false for new pages. So i copied code from 'autho_aug' to new scheme 'autho_sept', & it worked for new pages. I don't understand if code is same for both scheme, why required to use two different schemes.
Now i have added few more pages to application, and facing problem mentioned earlier.
any solution for both the problems.....

Answer 1

Hi,
Let me clear my problem once again.
-->Home page i.e. P2 does not use authorization, So it is displayed along with text item :p2_user_privilege.
-->Then user click on one of the links , Now page :P70: should get displayed.
P70 is using authorization scheme.
-->But :p2_user_priviledge value is not accessible at authorization scheme, I dont know why.
I could not find out where to create Application item , as suggested by you.
& not able to find Developer menu , session at home page as suggested earlier.
And one more question, my application at runtime display
X en us
at bottom
How to make it
USER: X Language: en us
Like in development environment.
Hope I have cleared my problem, waiting for reply.
