We would like to force our users to use the condition pop up dialog to edit the visibility of a question and not have the ability to manually type in the conditional expression. This is due to training; we've found the manual editor to be daunting whereas the pop up dialog is much simpler to understand. I know the manual editor allows for more complex expressions but the conditions for our use case are simple enough to be covered by the pop up dialog.
I tried the allowEditExpressionsInTextEditor: false
option and it disables editing the conditions entirely (which disables the button that opens the popup). Calling Survey.Serializer.getProperty("question", "visibleIf").readOnly = true
has the same result.
Thank you!
