I first noticed this error after upgrading from APEX 24.1.7 to APEX 24.2.0, but I can also replicate on apex.oracle.com (24.2.5). The error did not occur on APEX 24.1.7.
I have a Content Row region on my page that does not have any data in it, the Pagination Type attribute for the region is set to ‘Scroll’. When I scroll up or down on the page the following error is shown in the browser console:

Error text is: Uncaught TypeError: Cannot read properties of undefined (reading ‘top’) at modelViewBase.min.js?v=24.2.5:5:33854
If I change the Pagination Type to ‘Page’, the error does not appear.
Steps to Replicate:
- Create a new blank page
- Add any region to add some height to the page to force a scroll
- Add a Content Row region below. Query can be anything but make sure it does not return any rows. I used SELECT * FROM dual WHERE 1 = 2;
- In the region attributes change the Pagination Type to ‘Scroll’
- Save and run the page
- Scroll down the page and the error will be shown in the console.
Any idea how to stop this from happening (apart from changing the Pagination Type to ‘Page’)?
Kind Regards,
