Design Studio 1.6 - PANEL.setVisible() not working

Hi all,

We've recently upgraded our dev environment to Design Studio 1.6. After the upgrading, we opened the old Design Studio Object (created using DS1.5) to see if there are any inconsistencies.

I ran into the below JavaScript Error, and after some investigation, found that it is being caused by one line in our script:

MAIN_PANEL.setVisible(true).

The application is a simple one (although it has a lot of datasoruces) and uses no SDKs.

Has anyone else encountered this issue post-upgrade to DS1.6? Is there already an SAP Note that addresses this issue?

Thanks in advance.
