Good Day!

My PB application deploys to PowerServer Web with no errors. I can run the application and it connects to the database. The frame looks great. However...

From that point forward, things are strange; no user objects are created, no data can be retrieved... but no errors are encountered! It's so weird. I can open every window in the application, but none of them display any of their data or user objects... 

Is there a ways to get something like PBDebug output while running in PowerServer?

Hi Tom,

it is quite normal a Web application does "nothing".

It usually happens because, as you say, user objects are not created and their code is not executed.

If any (Javascript-related) error is fired, you can increase the visibility level by displaying popups, go to AEM -> Client features and scroll to Error Message Mode.

However, as Chris suggested, debugging is the best way to investigate. Enable Appeon debugger and find the line of code that alters the application workflow.

Please take into serious account the Unsupported Features Report. If a user object contains unsupported feature it might not get created at all. Not to mention the handling of NULL values in boolean conditions or string/math operations, which can also produce different runtime behaviour (search for "NULL" in the Appeon PB help).

Last option, kinda slow&rude but definitively effective, is to insert MessageBox(). If you don't see it, wrong execution flow happened beforehand.

Hi Marco - Thanks for this info. When I run my Analysis on my source and get "Have to Modify / Unsupported", it seems that even though that code is wrapped with IF ( AppeonGetClientType( ) = 'PB' ) THEN, the unsupported code still appears in the Unsupported Feature Analysis Report. May I safely assume that as long as the unsupported code does not run that things should still work in PowerServer Web? Thanks, Tom

Yes, you may always get that message. What I did in my frameworks though was to isolate the commands that were PB Native vs PowerServer in different libraries and then dynamically instantiate objects based on PB vs PS. I then created different targets for PB vs PS. That allowed me to always have a clean full build / deployment.

Hi Tom;

  There is no application "Profiling" feature for PowerServer based Apps. However, you can use the PS Web Debugger .... https://www.youtube.com/watch?v=ygGlWw4bpQM
