Hi @Michael_L_Barnes and @Elena_ONeil, thanks for bringing this issue to our attention.
Disabled Message not Displaying - Logged
I’ve been able to reproduce this issue externally where the disabled message for buttons and fields doesn’t display and I’ve logged it in our internal tracking system. We’ll let you know if the issue is resolved. For now I’ve marked the customer impact as Level 4 - Medium - let me know if this sounds appropriate and if this blocking any active development projects.
Note: If a table or a form is in edit mode, then the field disabled message will display, but at the very edge of the field area.
App Composer issues - Need steps to reproduce & test page xml
For the other issues with moving fields around in forms and using model search, next time it happens try to remember what you were just doing beforehand so we can figure out how to reproduce and log the issue. If you’re able to reproduce and can provide test page XML with steps to reproduce that would be great. We’ll also keep our eyes open for these issues and see if we can establish a pattern.
