Syntax for APEX_PLSQL_JOB.SUBMIT_PROCESS with an OUT parameter

Question

Hi All,
I am using APEX_PLSQL_JOB.SUBMIT_PROCESS and calling a procedure that has both an IN and an OUT parameter.
The IN parameter works fine; I am able to call my procedure from APEX and pass it the :APP_JOB item as the IN parameter. The OUT parameter I can't get working. I can call my procedure from a different block in SqlDeveloper and everything works, so I'm confident that my procedure code is correct. I just can't get the OUT parameter returned via APEX.
This is the plsql code that I'm calling from an APEX dynamic action:
DECLARE
  l_sql      VARCHAR2(4000);
  l_instance VARCHAR2(30);
   l_job number;
  l_rows_processed number;
BEGIN
l_instance := :P9_INSTANCE;
  l_sql      := 'BEGIN update_tl_tables_1(:APP_JOB, :F103_ROWS_PROCESSED); END;';
  l_job      := APEX_PLSQL_JOB.SUBMIT_PROCESS( p_sql => l_sql, p_status => 'Background process submitted');
l_rows_processed := :F103_ROWS_PROCESSED;
insert into gse_lng_jobs (instance, job_id, rows_processed) values (l_instance, l_job, l_rows_processed);
COMMIT;
END; My procedure is created as:
create or replace
procedure UPDATE_TL_TABLES_1 (l_app_job IN number, l_rows_processed OUT number)
IS......Again, this works fine from SqlDeveloper. Can anyone suggest the proper plsql code? I've tried this using a page item, a system item etc. and no luck. I first tried just passing my procedure a local variable like l_rows_processed, but the procedure wouldn't even run, so I'm assuming the API needs an actual APEX item but I'm out of ideas here.
thanks in advance,
john

That's not going to work because the job hasn't run yet when you perform the insert. So :F103_ROWS_PROCESSED wont contain anything useful.
Why don't you try performing the insert as part of the job, e.g.
l_sql := 'BEGIN update_tl_tables_1(:APP_JOB, :F103_ROWS_PROCESSED); insert into gse_lng_jobs (instance, job_id, rows_processed) values ('''||l_instance||''', '||l_job||', :F103_ROWS_PROCESSED); END;';
...something like that.
