Hello

I seem to be experiencing a problem on a page in an application, whenever the page is submitted it causes a HTTP 404 error.

On the apache logs the error shows as;

mod_plsql: /pls/htmldb/wwv_flow.accept HTTP-404 ORA-06550: line 22, column 3:\nPLS-00306: wrong number or types of arguments in call to 'ACCEPT'\nORA-06550: line 22, column 3:\nPL/SQL: Statement ignored\n

After reading the forums I eventually arranged to get the shared pool flushed, which did fix the problem temporarily. However after a day the problem returned.

I then started to test the page to see if there was any indication of what could cause it, I removed all the javascript and PL/SQL code, which left me with 2 regions (1 visible region with a radio submit and a text field, and 1 hidden region containing a couple of hidden text fields) and a unconditional branch to the same page.

The problem still persisted, however if I reordered the region display sequence the problem stopped and the page submitted as expected. (It would also work if I reordered just the radio button and text field)

I have changed the order on the original page that contains all the javascript and PL/SQL and the HTTP error no longer occurs.

Any ideas what would cause this error?
