Schema name and object name quoted together in MRU after v3 to v4 upgrade

Question

After upgrading from v3 to v4 an app has a system generated Multi Row Update function that is broken;
PL/SQL : ORA-00972: identified is too long
declare
  function x return varchar2
  is
  begin
    begin 
      for c1 in ( select "MY_SCHEMA.MY_SEQUENCE".nextval pk from dual ) loop
       return c1.pk;
      end loop;
    end;
    return null;
  end;
begin
  dbms_output.put_line(x);
end;Note the Schema Name and the Object Name have been quoted together!
Is this a known issue and do you know of a fix?
Many thanks in advance
Craig

Hi Craig,
this problem is not known so far.
I had a look at the code and that change has been made because of multi byte support for sequence names and because of security reasons.
We try to avoid breaking changes in applications, but it looks like we haven't expected that developers are specifying sequence names prefixed by the schema name.
Maybe the following workaround is feasible for you:
1) Find all tabular form columns which are using a sequence with a schema prefix as primary key source
select *
  from apex_application_page_rpt_cols
where primary_key_column_source_type = 'S'
   and instr(primary_key_column_source, '.') > 0;2) Go to that tabular form column and remove the schema prefix
3) If the sequence is really in a different schema than the parsing schema of your application, create a synonym for it.
Hope that solves your problem.
Regards
Patrick
