Refreshing PL/SQL Regions in APEX

If you've been using APEX long enough, you've probably used a PL/SQL Region to render some sort of HTML that the APEX built-in components simply can't handle. Perhaps a complex chart or region that has a lot of custom content and/or layout. While best practices may be to use an APEX component, or if not, build a plugin, we all know that sometimes reality doesn't give us that kind of time or flexibility.While the PL/SQL Region is quite powerful, it still lacks a key feature: the ability to be refreshed by a Dynamic Action. This is true even in APEX 5. Fortunately, there's a simple workaround that only requires a small change to your code: change your procedure to a function and call it from a Classic Report region.In changing your procedure to a function, you'll likely only need to make one type of change: converting and htp.prn calls to instead populate and return a variable at the end of the function.
