I needed to downgrade my Lotus Notes client from 8.5.3 to 8.5.2 to verify some functionality works in the earlier client. After doing this, any JavaScript included in my XPages, from a simple alert() prompt to the loading of Dojo, no longer works. I've completely uninstalled 8.5.2, rebooted and reinstalled the client, to no avail. Weird thing is, JavaScript does work in my Notes client in a simple page.
I've double-checked, and my Notes client preferences are set to run JavaScript, and my ECL entries show every legit signer as being able to run JavaScript. The databases I've tested so far all have "Use JavaScript when loading pages" enabled.
Any idea what could be going wrong?
