Just started with Pega and I often get errors while previewing the application I build. Is there any way to get more detailed errors/logs rather than just "java.lang.NullPointerException"?
I'm trying to get a better understanding rather than fix any specific error. Is it possible to view the underlying code that's created when building applications with Pega App/Dev studio? Is there a console or error log that would give me a better way to pinpoint where I went wrong? Is there any resources or guides on how to debug better?
There are two built-in tools that will help you with debugging: Tracer and Clipboard. The former shows you which rules are involved, the order in which they are called, and data passed in/modified by certain rules, as well as the entire stack to help you track down any error. You can decide to show/hide rules, set breakpoints, and more.
The Clipboard allows you to inspect data that is associated with an application - for example fields, data pages, and much more.
