Oracle Report Failing After Database Version Upgrade

Question

Hi,
I have function code created in RDF file of oracle reports 10g as below-
create or replace function clobblobtest (TMP_MID varchar2) return varchar is
missed_text varchar2(1000) := '';
v_time_stamp date;
v_end_time date;
cursor c1(c_time_stamp in date,
          c_mid in varchar2) is
       select mn.TEXT from msgnotes mn
  where mn.mid=c_mid
      and mn.create_date >= c_time_stamp;
cursor c2(c_time_stamp in date,
          c_mid in varchar2,
          c_end_time in date) is
       select mn.TEXT from msgnotes mn
  where mn.mid=c_mid
      and mn.create_date >= c_time_stamp
      and mn.create_date <= c_end_time;
begin
  IF ('1' = 'INWARD RETURN') then
    select bbi into missed_text from mtf1000 where mid=TMP_mid;
    ELSIF '1'='QPH Missed' then
  Select max(nj.update_date) into v_time_stamp
  from newjournal nj
  where nj.mid=TMP_mid and nj.status = 'CTOVRQ';
  for i in c1(v_time_stamp,TMP_mid) loop
  missed_text:=missed_text||' '||i.text;
  END Loop;
  ELSIF ('Rejected'='Rejected' OR 'REJECTED'='REJECTED') then
  IF ('TERMINATED' in ('TERMINATED')) THEN
  Select min(nj.update_date),max(nj.ENDDATE) into v_time_stamp,v_end_time
  from newjournal nj
  where nj.mid=TMP_mid and nj.actionid2='16' and nj.actionid1 is null;
  for i in c2(v_time_stamp,TMP_mid,v_end_time) loop
  missed_text:=missed_text||' '||i.text;
  END Loop;
  ELSE
  Select max(nj.update_date) into v_time_stamp
  from newjournal nj
  where nj.mid=TMP_mid and nj.status = 'UNSETLED';
  for i in c1(v_time_stamp,TMP_mid) loop
  missed_text:=missed_text||' '||i.text;
  END Loop;
  END IF;
  ELSE missed_text := null;
  END IF;
return(missed_text);
End;
Note:- Text column from table msgnotes is of datatype CLOB.
I have executed report having this function before oracle upgrade and it works fine.
But when i am trying to execute report after oracle version upgrade from 11.2.0.3.0 to 11.2.0.4.0 with same data report fails with runtime error Rep-1401: '' Fatal PL/SQL Error.
With New version we tried to typecast Text column from clob to varchar and executed report then it works... but report runs on old version without any explicit typecasting.
Please note when i run and call this funtion from sql developer with upgraded database version it works fine.
Please advise.

This error can possibly depend on the fact that the PL/SQL engines are in different versions. When using SQL Developer you use the PL/SQL engine in the database. When using Oracle Reports you use the PL/SQL engine in the Oracle Reports Server (Web Logic Server even maybe). These versions - in the Forms and Reports realm - are different (read: a lower version) than the PL/SQL engine in the database.
If I check what version I have in Oracle Forms, as an example, I get 11.1.0.7.0 (Help in the Oracle Forms Builder menu) but in the database I have (select * from product_component_version;) 11.2.0.3.0.
That COULD be your issue...how to fix it I am not sure...
