Sometimes you just feel like you would be a newbie in coding business applications. Luckily it doesn't happen so often anymore. But this time it hit me hard. :)
During an application upgrade on Universal Theme I discovered an ugly workaround to create custom error messages I used in that time.
The old code looked like that:
Anyway on Universal Theme it looked not so nice anymore because a "success message" has always a green background color. Putting some red text color above is not the user experience I would prefer.
I searched for about 3 minutes and found a really good article from Jorge Rimblas writing about the APEX_ERROR package. The blog post is from 2013 so this procedure must be available for a while now. What made me feeling like a jerk. The good side is that I now can start again to climb up on the iron throne. :)
The updated code looked like that:

During an application upgrade on Universal Theme I discovered an ugly workaround to create custom error messages I used in that time.
The old code looked like that:
declare
retval number;
p_cust_id number;
p_status varchar2(30);
p_upduser varchar2(10);
begin
p_cust_id := :p1_cust_id;
p_status := 0;
p_upduser := :app_user;
retval := cust_apex_pkg.cust_apex_fnc ( p_cust_id, p_status, p_upduser );
if retval = 1 then
apex_application.g_print_success_message := '<span style="color: green;">Order was successfully published.</span>';
elsif retval = 2 then
apex_application.g_print_success_message := '<span style="color: red;">Error: Custom error 1 occurred.</span>';
elsif retval = 3 then
apex_application.g_print_success_message := '<span style="color: red;">Error: Custom error 2 occurred.</span>';
else
apex_application.g_print_success_message := '<span style="color: red;">Error: Unknown error occurred.</span>';
end if;
commit;
end;
As you can see I used the apex_application.g_print_success_message to overwrite the text color. Quite ugly but it worked as expected.
