Error verbosity when page causes a 404? (APEX 2.2.0)

Hi all,
I have a select list. That select list has an SQL expression that is evaluated to determine if the item will be rendered as "read only". I have a PL/SQL region that assigns a value to that page item earlier. If the query returns integers for the return value, but I attempt to assign the page item to a string, I get a 404 when the page loads.
Obviously, the answer is not to set the page item to a string. Here's the question: is there a way to get a more verbose error out of APEX than a 404? (I get 404s from time to time and I have to go searching around to figure out why.)
Thanks,
Don

Hi Don,
If you'd like to display more information in the page then you can add the line -
PlsqlErrorStyle DebugStyleto your DADs file.
Note however that this is only really for development, you almost certainly wouldn't want to do this in your production environment (for obviously reasons, it's much better to use the Apache logs etc in your production system).

Apex 4.1 Custom error function and page rendering

Hi
I have setup a demo application at http://apex.oracle.com/pls/apex/f?p=19820:1 which is a simple testing application for testing of the apex_error_handling_example function Patrick wolf put into Oracle documentation. I have setup a error on the page rendering of page 2 in the application. The error process contain this simple error code declare
v_id number;
begin
select 'x' as one into v_id from dual;
end;
which generate plsql numeric or value error. The process is running before regions on page rendering on page 2. I have also created the same error process on page processing before DML processing on the page. When i insert apex_error_handling_example into the application level and run the application the error is not caught and the page is rendered as nothing was wrong. When the page is submitted the error function is executed and work correct.
When i remove the error function from the application the error is caught and displayed on the APEX error page with the detail link for drill down to show more about the error.
Any which can tell what is wrong with the setup i have done. The error function apex_error_handling_example setup is simply a copy/paste from the documentation with some few debug message put into a logging table.
kindest regards
jon

Hi
Yes, when you submit the page the page processing is displaying the error message inline, but it does not show the same error on page rendering for page 2, if i remove the custom error function it will show the error on APEX separate error page. The debug output from the page 1 is as following:

Fox opens an error (Problem opening page) page when ever I open a new fox window and parks it in upper left corner of my desktop, what is up with this ??
It slows down my surfing, a lot and I do not notice the error page, until I notice the slow speed, because it is as small as a page can be, showing only the " -, +, & full size boxes with a border"

A problem has caused it to stop working. Windows will close the program and notify you of a solution." When I used the trial I never received this message. Now after purchasing it I receive this error each time I open PP and am unable to use. it. Any ideas or support to fix this issue?

Adobe updates: I've gotten error messages when trying to download pdfs (very annoying). Read somewhere that mac os has problems with the adobe extensions, thus, causing error messages from adobe. I ignore the updates. Should I?

Hi All,
I have stopped updating adobe software b/c I read that the adobe update software inserts extensions into the mac software system, causing annoying/time consuming error messages when downloading new pdfs. I get adobe update notices 2-3x/week. What do you recommend? I use an iMac OS 10.94.
thanks for your help.

Preview will do all that and is part of the OS.

With Adobe, if it's working, then it should be fine. See here

I created a brochure in pages and exported it to a pdf format. The pdf looks and opens perfectly using preview but when opened in adobe reader (which my printer uses), fonts look odd, transparencies don't display...etc. Tells me error exists on page?

I created a brochure in pages and exported it to a pdf format. The pdf looks and opens perfectly using preview but when opened in adobe reader (which my printer uses), fonts look odd, transparencies don't display...etc. Tells me error exists on page?

Does this essentially mean there is no way to fix this problem on my end? It's a pity because the design and branding of my brochure will suffer if I remove transparencies and use different fonts. It also concerns me moving forward because it means the quality of print on my pieces will be significantly lower because most commercial printers use Adobe products.

Error message when moving to a different page

Post Author: EvDev
CA Forum: .NET
I have an ASP.NET 2.0 and Crystal Reports 11.5 project that works fine
when it's being debugged and when it's on our test server, but when we move it
to our production server the user will receive an error message when moving to a
different page of the report. It's an
"Object reference not set to an instance of an object". It seems very
odd for me for something to work on the test server but not on production. Has
anyone seen this before? Thanks

Hi there,
This does seem like a very valid process to be sure
I'm guessing that the fix is shown in "Solution 1" in this doc;

To proceed, please select the Home link at the top of the application page to return to the main menu. Then, access this page again using the application's navigation controls (menu, links, and so on) instead of using the browser's navigation controls like Back and Forward.
Can somebody help me to solve this problem.
Thank you very much.
