Fetch Error but the row exists

Question

I have an application when you go to the next page, you sometimes get the following error:
ORA-01403: no data found
Error Unable to fetch row.
OK
I then edit the page and run it without making changes, and it works with no errors. It happens on two particular pages.
The application is on apex.oracle.com
Workspace: RGWORK
Application: 41368 - Online Certification Application
Username: TESTER
Password: test123
Start with page 33
Select last checkbox (Small Business Enterprise) and click on start application
The next page, Name and Address (page 2) will be displayed. Fill out all the information and click on the "Next Question" button.
I usually get the error on the next page (Page 27) or the following page (Page 28)
Can someone please help me?

Answer 1

I think the problem is that your ARF processes are firing after part of the form is painted. Change them to fire After Header.
A related problem (which I fixed in page 28) is that the metadata for the DML Fetch Row process on page 28 was corrupted. If you export the page, or application, you'll see this:
p:=p||'#OWNER#:OCA_FIRMS:P28_FIRM_ID:FIRM_ID|U';
begin
p:=p||'#OWNER#:OCA_FIRMS:P28_FIRM_ID:FIRM_ID|U';
wwv_flow_api.create_page_process(
  p_id     => 4630220837539919989 + wwv_flow_api.g_id_offset,
  p_flow_id=> wwv_flow.g_flow_id,
  p_flow_step_id => 28,
  p_process_sequence=> 10,
  p_process_point=> 'AFTER_SUBMIT',
  p_process_type=> 'DML_PROCESS_ROW',
...The first assignment statement, above, was this before I fixed it:
p:=p||'F|#OWNER#:OCA_FIRMS:P28_FIRM_ID:FIRM_ID|U';
That 'F|' is incorrect. We are aware that this happens sometimes but are not sure exactly how.
