I am working on NAV 2018 CU 2. I had set the Editable as false in the table but that didn't work. It still allows to edit in the RTC but if Editable = false is set in the page it works fine.
Same experience here.
This should be fixed, because this is a show stopper now when converting our C/AL code.
Thanks for reporting.
This bug has been fixed in February Dev Preview. The support team ported the fix back to NAV 2018 CU4 as well
I have tested it on NAV 2018 CU04, it still happens. I set up editable = false on my new table, but the field is still editable on the page...
My bad, this hotfix will be part of CU5 and not CU4.
